Hard water plays a crucial role in plant growth and development, as it can interfere with nutrient uptake, alter soil pH, hamper root health, lead to mineral buildup in the soil, and affect water penetration. The hardness of water can range from mild (less than 100 ppm) to severe (more than 150 ppm). Poor quality water can result in slow growth, poor aesthetic quality of the crop, and even gradual plant death.
High soluble salts can directly injure roots, interfering with water. Plants stressed under a water deficit show a decrease in photosynthesis, which is related to decreased growth and increased incidence of early senescence in plants. The ratio between biomass accumulation and water consumption is known as water use efficiency and is widely relevant today in fields such as plant improvement, forest ecology, and climate.
Hard water can also negatively impact plant growth and health by affecting nutrient uptake, altering soil pH, hampering root health, leading to mineral buildup in the soil, and affecting water penetration. Proper management and the right plants can help plants thrive. The minerals calcium and magnesium can be beneficial for their growth, depending on the hardness level of water and the type of plants being grown.
In addition to these negative effects, hard water can also increase the risk of disease. It is high in calcium and magnesium, which are essential micronutrients that often go missing without proper watering. Chlorine also has a significant impact on root health, as all beneficial bacteria and elements are lost.
Hard water can also create an unsightly white crust on soil and pots, damage plants, and cause a buildup of salt in the growing medium. Variations in pH during cultivation can also affect the growth and quality of plants. Therefore, it is essential to carefully manage and maintain the right water conditions for optimal plant growth and health.

Is water hardness 7 bad?
Hard water is a condition where water hardness is measured on different scales, either grains per gallon (GPG) or parts per million (PPM). Soft water is 0-3 gpg, moderate water is 3. 5-7 gpg, and hard water is 7. 5 gpg and should be treated with a water softener. Proactively addressing hard water problems can prevent plumbing issues and inconveniences. To detect hard water, contact the local municipality or water utility for a free report or purchase a water test kit.
If the water is hard, a water softener can be installed. Water hardness is determined by the concentrations of calcium or magnesium in the water, which are high enough to affect the home’s plumbing. If the water tests as hard, follow the lead of other homeowners and consider installing a water softener.
What is the main problem with using hard water?
Hard water is a condition where water absorbs minerals from rocks and soil, such as calcium and magnesium, which can make soap less effective and lead to limescale buildup. This buildup reduces water pressure and flow in pipes, affecting the efficiency and lifespan of appliances that require water for operation. Water hardness is measured using grains per gallon (gpg), with 0-3 gpg considered soft water, 3.
5-7 gpg moderate and ideal, and 7. 5 gpg hard water, which should be treated with a water softener. This affects the efficiency and lifespan of various appliances, including coffeemakers, water heaters, and refrigerators.
Is water stress too much water?
Water scarcity is a global issue, with the United States facing water stress due to its proximity to draining its water supplies. The country’s water quality is degrading due to increased forest fires and anthropogenic activities, leading to public health concerns. The Colorado river, which supplies 22 million people, is experiencing significant water levels drop in Lake Powell and Lake Mead in Arizona.
The US faces water risks, as indicated by the Water Risk Atlas, which indicates high regional water stress and nutrient runoff issues in the Finger Lakes region and other coasts. Some US states, like California and New Mexico, are facing significant strain on their water supplies due to rising global temperatures. Florida, on the other hand, has “too much” water and is flood-prone, making safe water inaccessible.
The US is placed at 71st with a low to medium water stress, based on data from 189 countries. The withdrawal and replenishment of water varies significantly within the country, leading to a supply-demand mismatch. The water withdrawn in the US is less than 20 percent of the overall water supplies, but resources are withdrawn at a faster rate than replenished. Factors like global warming and mismanagement contribute to the overall water stress. Southwestern states, such as New Mexico, are in the riskiest position due to their naturally arid nature.
What is a disadvantage of soft water?
Soft water is generally considered harmful if consumed regularly, as it can increase sodium levels, leading to health issues like blood pressure. The process used to make soft water makes it more volatile, attracting unwanted elements like lead. A water softener can waste up to 120 gallons of water per 1, 000 gallons, potentially increasing your water bill. However, soft water has several benefits, including less damage to skin and hair, cleaner clothes, reduced scaling and lime build-up in sinks, dishwashers, and tubs, and can save money on energy bills.
It also prevents scaling build-up in pipes, allowing hard water to be used for drinking and cooking. Ultimately, combining a water softener with a separate drinking line can provide the best of both worlds. For more information, consult a professional plumbing and heating provider.
How does water affect the growth of a plant?
Plants require water for growth, as they are approximately 80-95 water molecules. Water is essential for photosynthesis, cooling, and transferring minerals and nutrients from the soil to the plant. Plants, including fruits, vegetables, and grains, require water for various reasons, including photosynthesis, cooling, and nutrient transport. We can grow food without fossil fuels, but we cannot grow food without water.
Plants provide food for both humans and animals, such as cows, chickens, and pigs. Water is essential for growing corn and cows, as well as for other crops like fruits and vegetables. To access student materials, students should point them to the Student Version, download them in various formats, or use InTeGrate teaching materials.
What is the disadvantage of hard water?
Hard water has numerous benefits for the human body, including strengthening bones and teeth, reducing constipation, and improving gut health. However, it also has numerous problems, including soap scum, cloud-like stains, clogged pipes, dry skin, faded laundry, and corrosion. Temporary hardness can be removed by boiling, while permanent hardness requires other methods like Clark’s process, Calgon process, and ion exchange resin.
Is higher water hardness better?
Hard water, rich in magnesium and calcium, can help meet the recommended daily intake of these essential minerals. While there is speculation about cardiovascular benefits, there is no definitive conclusion. Drinking water with lower magnesium and calcium concentrations is safe if your diet includes these minerals. If you have deficiencies, taking multivitamins or calcium or magnesium supplements may be sufficient to meet your daily needs.
Is soft water better than hard water?
Hard water is not as important as soft water in terms of health, but it can cause damage to plumbing and appliances. Unfiltered water can also cause health issues. To address both, it is recommended to install a water filtration system, such as those from HomeWater, which softens water while filtering it for pathogens, chemicals, and other harmful elements. This solution can help protect your home and prevent potential health issues.
What happens if water hardness is high?
The Vermont Wastewater and Potable Water Revolving Loan Fund, also known as the On-Site Loan Program, is available to certain Vermont residents for the repair or replacement of failed water supply and on-site wastewater systems. The program is funded and administered by the Agency of Natural Resources, Department of Environmental Conservation, with loan underwriting and servicing provided by the Opportunities Credit Union in Winooski. Eligibility requires a failed drinking water supply and a year-round residence living in the residence. The family income cannot exceed 200 of the state median household income.
The NeighborWorks Alliance of Vermont offers full affordable housing services for income-eligible individuals, including assistance for water treatment systems, well drilling, and septic system repairs. The program is administered by the Rural Development office of the U. S. Department of Agriculture and is for low-income families living in rural areas or communities with a population of 25, 000 or less. Individuals aged 62 years or older may qualify for grants or a combination of loans and grants, while younger applicants are only eligible for loans.
How does water stress affect plant growth?
Long-term water stress can cause plants to wilt or stop growing, with diminished crops, discolored leaves, flower buds, and flowers. These plants may eventually die, and they may show the effects of weeds, insect pests, and diseases. Symptoms can vary with different types of plants, and woody plants may experience yellowing, wilting leaves, burning or scorching on leaves, dropping some or all leaves, and appearing dead.
Most established woody plants recover when watered, but some may still recover when watered. To determine if a plant is alive, scrape the outer layer of a twig or bark, wait until the following year, and do not remove it in the first season.
What will happen if you put too much water in your plant?
Over-watering can lead to root death, slow growth, yellowing leaves, leaf scorch, leaf burn, water-soaked spots, oedema, and root rot in plants. To prevent this, deep watering is recommended, allowing roots to reach deeper into the soil for cooler conditions. Watering should be done less frequently but for longer periods to promote healthier plants. Water-conserving drip emitters or soaker hoses can be used to conserve water, and adjustments should be made based on season, temperature, and rainfall. Overhead watering can also promote fungal disease. Additionally, ensure that leaking irrigation pipes or downspouts are not causing soil to become too wet.
📹 Nitrates and Water Hardness – Two Problems that DO NOT EXIST!
In this insightful video hosted by Father Fish, two crucial topics in aquarium maintenance are explored. Firstly, the video delves …
This is great info. Just to point out that the hard water or high pH is not the actual problem here as the vast majority of plants will adapt and grow very well. Plants even use carbonate and bicarbonate compounds (KH) within the water as a source of carbon for photosynthesis. The actual issue is that plants also need food to grow and the common ferts that are dosed, e.g., micro or trace where the FE iron is EDTA that precipitates at pH 6.5/7 and iron is simply unavailable. So, a low-tech hard water aquarium is less forgiving with an inbalance of light and nutrients. Alternatives to the above iron is FE DTPA (which is 60% unavailable at pH 8) or FE eddha (maintains iron availability to plants past pH 9.0 but it will tint water reddish) or ferrous iron gluconate I.e seachem flourish Iron (degrades very quickly). Other than that, magnesium and potassium are usually lacking. Nitrate and phosphates are not generally needed with an average stocked tank.
I didn’t even try plants when I had 7.8 and very hard water, but I’ve seen others have success, especially with CO2. Where I live now I am around 7.1 but a gh over 300… and growing plants really well with or without co2. Light and proper ferts more important in my personal experience – my one tank with a poor light from a kit isn’t doing as well as my others. But even that tank has Jungle val doing runners… in sand. It can be done!
I’ve learned a lot of this the hard way. I feel like there is still much to learn. Because of injuries and surgery I ended up only being able to do water top offs for like 4 months. Many master aquarist can do it, why can’t I? Things started dying – including duckweed. I bought a TDS meter. One tank had a TDS of 1600 ppm. I am slowly lowering the TDS in my tanks. The problems are complex and too extensive for here but yes, know what GH and KH are. Again, this is complex.
Dan, I can relate to what you are saying. Many of my aquariums have hard water & higher pH ~ 7.6 Most of my plants do well, but I noticed if the pH does indeed go higher, my aquatic plants will struggle a bit. Typically, the GH & KH have been around 200 ppm, on average. Mostly keep these water parameters for my hard water & higher loving pH fish. Plants are generally a secondary item for me. As mentioned it is the carbonates that affect the pH, but am wondering at what level will the GH, overall, start negatively impacting the plants? Have experimented in my aquariums with this, but usually the GH would be <250ppm, without noticing any plant deficiencies. Never had the GH higher, so cannot comment further on that. BTW, On a side note: Was out fishing today & caught some nice bluegill fish. It rained all morning, but the fish were biting at least. Good article. 📊📈👍📺😎
Interesting! Made me interested to test my ph in the substrate itself now. I have tap water with a ph of 7.6 and is moderately hard, usually 150-200ppm whenever I check and in general I don’t tend to have plants struggle. Instead of algae when I have a struggling plant I usually see a kind of crust form on the leaves which I always assumed was a calcium or other mineral build up now the plant is not using nutrients or is getting prevented from using nutrients some how. Thanks for the article, going to be doing some tests now I’m curious
I am in Philadelphia, my hardness is good, but low ph in my tap water, I noticed my plants were melting like crazy or just dying off, my local fish store me told me to up my ph with crushed coral, my ph was tested by myself and store to be at 6.5, so I bought some coral and I will be doing that this weekend, I’ll let ya know of the results if you want, and be a while to see how plants are doing.
Yeah, I coulda told you all that 😋When you were like “plants have trouble in hard water”, I was like “Huh? Maybe he’s struggling with ph or doesn’t know that there are hard water plants and softer water plants?” I have hard water and ph can be a bitch, though as you mention, it has little to do with gh. In fact, soft water plants grow fine in hard water and may even appreciate the extra mineral content; Meanwhile, hard water plants like hornwart do poorly in soft water or may even die, and even jungle val may do poorly because even though ph in substrates tend toward neutral over time, hard water plants foliar feed certain nutrients, and many of them feed on bicarbonates (alkalinity) for their carbon source rather than just relying on co2 gas. Kh on the other hand can effect ph, though that’s where I’ve had some difficulty, since you can end up bottoming out kh in order to control ph, and you need a decent amount of kh for buffering, especially if injecting co2 for soft water plants. To make matters worse, some of your carbonates can convert to bicarbonates or vise versa so that it can be hard to keep kh from being too high. But yeah, I don’t know if I sound smart, but I’m not exactly a chemist or an aquatic ecologist, so I’m still more often than naught feeling like a monkey on a football trying to figure this out. One of the better options might be to make your own hard water by starting with RO, rain, or distilled water and adding calcium carbonate, magnesium sulfate (epsom salt), potassium chloride powder (you can get this at a health food place), and perhaps combining that with a store bought RO reconstitute that adds trace elements to the water.
I have a aged tank it’s had all kinds of creatures and what i’ve noticed is that when my tank is overstocked, as it is currently. the nitrates build up and become acidic. I’ve always run a non reactive substrate, the tap water comes out 200+ppm gh. when i tested my tank i realized that i had no KH, and my hardness was still 200ppm+ aside from the obvious, water changes, i’ve started using a little crushed coral (or aragonite) this insn’t going to solve my ph issue, but just give me some time until my 110 is cycled 🙂 tldr: Nitrates can cause low pH even if the water is 200+ppm gH
My tap water (I can’t afford a RO system, nor can I carry tons of rain water) is acidic but very hard, in Tampa Bay area of Florida. When I do water changes I add baking soda, so my PH is neutral. After testing, my parameters are great, except my GH is off the charts. I recently saw something about putting sphagnum in mesh bags into the tanks. Any ideas on how to reduce that GH?
Interesting! I have low KH, moderate to low PH, and hard water. Due to having such a low KH I have to be really careful not to add too much drift wood or calcium containing rocks. I can’t keep most stem plants alive. I have a couple crypts that seem to be doing well, as well as some S repens. My red roots did not do well…but my frogbit is thriving. I am thinking, if I add more mystery snails, they may aid in absorbing calcium? Hopefully, this will be helpful as shrimp simply will not survive. I also go rid of all of my white veined rocks. I’m looking into getting dragon stone or possibly smooth river rocks instead. Any thoughts? Thanks!
I think you have just explained why my crypts won’t grow well at all – not dead but sick looking all the time. My water is PH8, KH 7, GH 10, local river near me is even harder. I dose Seachem liquid ferts and use ADA soil and all other plants are doing well except I have noticed Ambulia is not keen on hard water either. Tank is 9 months old. I now mix 50% rain water to bring the PH down a bit. My observations on my hard water (Outback Australia location) is: Jungle Val, loves hard water (its a native) Lileaopsis Brasil and Brisbanica, loves hard water (its a native), these 2, the natives, grow like weeds in my water Hair grass dwarf (Brasil), loves hard water Java moss doesnt seem to care but I usually have in rain water. US Fissidens moss, loves hard water Xmass moss is OK Anubia, it seems to like hard water, but am not sure, haven’t had it long enough. Crypts I now have in rain water plus a bit of source water but they don’t look great. They are alive though. Just my experience. I expect crypts like an acidic substrate lower PH than I can give them and my rain water may be to void of anything they need.
My ph out of my tap is 7.8 but over time in the tank it goes up to 8.0 is that because of evaporation? I don’t have lids on my tank. I live near the ocean so my water has very high gh and kh. I couldn’t grow water fern floating in my water at all. I also have a big peace lily growing out of the tank- 0 nitrates- I think it is sucking up all the nutrients out of the water so no floating plants have been able to live. Except Anubias does great. Java fern shrinks in size and withers away. Crypt Wendii does fine. The bacopa and water wisteria seem ok but haven’t had then long.
very good info. I never thought about the fact that my ph might be lower down in the substrate than it is in the water column. I have about 3 inches of organic soil capped with about 2 inches of small grained sand for my cory cats and a variety of botias. I’m assuming that down in that earthy mix of organic soil the ph is low. My parameters are ph= 7.5, kh=5°, Gh=19°(super high) temp 80°, gallons 75, the tank is dirted and planted and about 6 years old. I looked at your article because I am exploring the water softening pillows by API. I’m concerned about my scaless fish and the sodium the product may put back into the water. Of course API (Mars) will not answer their phone number that they publish due to covid. I think that excuse is getting a little old. If all else fails I will just go back to adding distilled water to my water changes and try to slowly bring the GH down. Any thoughts?
Interesting article. I have hard water and a ph of 8.2. Only plant so far that have thrived in my aquarium is dwarf sag that is planted in eco earth. Java fern and Anubias petite have all died. That’s with dosing ferts once a week and really good lighting. Would adding co2 help fix the issue or would I be better off getting a ro/di system and mixing that with my tap water?
I’ve got a confusing situation here. My tap water comes in with GH of 12+ and pH 7.8 or more. However, kH is only 3 . I have no idea what’s going on here, could someone shed some light on this? Everywhere I check, people say that pH and kH are directly linked (more kH leads to higher pH) so I’m not sure what is causing my pH to go so high. Also, what plants / fish would thrive in these water conditions? Currently I’m ROing the water and using it for my neon and cherry planted tank, wanted to see if it was worth setting up a new tank (15gallon at the max) to match my water parameters.
Iv got high ph and hard water. It’s all about how balanced your tank is too via bio load and bacteria build up. Hard water tanks will suffer from to much nutrients. Iv got well water that’s got iron copper magnesium phosphorus (alot of plant fertilizers) that go in every water change I make 😢. I needed a bigger filter and more plants with longer water change intervals. I just let the plants do there thing now not just pile nutrients on top of more with water changes
