## Overview

Seachem Equilibrium 600g is a premium mineral supplement designed to restore and maintain optimal General Hardness (GH) in planted aquariums, especially those using RO or DI water. Free from sodium and chloride, it supports both fish metabolism and robust plant growth by providing essential calcium, magnesium, and potassium salts. Highly rated by over 1,400 users, it ensures a balanced, thriving aquatic environment.

## Description

Equilibrium™ is specifically designed to establish the ideal mineral content for the planted aquarium. Equilibrium™ contains no sodium or chloride (which can be detrimental to a planted aquarium at elevated levels). Equilibrium™ is ideally suited for use with RO (reverse osmosis) or DI (deionized) water or any mineral deficient water. Equilibrium™ raises the essential mineral/electrolyte content (General Hardness) of the water to balance with and promote stability of the carbonate hardness. To maintain KH, we recommend Alkaline Buffer™.Unlike competing products, Equilibrium contains NO SODIUM CHLORIDE. Both sodium and chloride are not rapidly depleted elements in a planted aquarium, and, in the case of chloride, can do more harm than good. Competitors’ products generally contain primarily sodium chloride (because it is inexpensive), which will raise the electrolyte levels for fish, but can be detrimental to plant growth. In addition, sodium is not a contributing cation to GH levels. Equilibrium™ contains only calcium, magnesium, and potassium salts, which aid in fish metabolism, but are also highly beneficial to plant growth.

Review: Seachem Equilibrium - Outstanding aquarium water conditioner that balances minerals and hardness to your tank's needs - *** Update 07/13/117 *** Back for more. *** Original review *** We have had an aquarium in our house for almost 25 years, ranging from 20 gallons to 110 gallons, and have had both fresh and saltwater setups. About 15 years ago we purchased our first Boesemani Rainbow and got hooked on this type of fish! Brilliant coloration from freshwater fish; now we have Boesemani, Turquoise, Banded, Red, and Praecox (neon) rainbows that have grown to about three inches in length. Our current tank is a 72 gallon bow-front which we fill with RO'd tap water. It has a bio-ball based biological filtration system and also a pond pump that runs water through a UV light canister to manage algae. About 2 years ago we moved into a new-to-us house, and within a couple month started to experience an oddity with the tank... no matter how much sodium bicarbonate we gently mixed in, we could not get the PH testing kit to read much above 6... and then we started to lose fish. Local aquarium staff were very nice to talk to, and they suggested that our issue was our tap water; they said that our county tap water has 0.5 - 1.0 dGH (General Hardness of about 17 ppm) and that rainbows like 10 - 15+ dGH (180+ ppm). They also noted that the RO process can also drive down GH, and that super low GH levels (or, conversely, super high GH) can cause false PH testing results. They recommended that we immediately cycle out 30% of our water and use Equilibrium to focus on getting GH up. I use a 5 gallon pail to do water changes, and the RO water pours into the pail as produced. We put the equilibrium into the pail with the new RO water, and stir aggressively with a long wooden spoon until fairly well mixed in. We cycled 30% of the water each week until the Equilibrium stabilized GH at around 200 ppm and PH settled in at about 7. As GH came up to around 100 ppm, the PH test results jumped to 8... so those good folks at the aquarium were right on!! Now we have gone back to normal water cycling and using a little bit of Equilibrium to maintain balance. For the last 20 months our rainbows have been quite happy and their colors outstanding once again. We even had a surprise birth... what looks like the fry from the turquoise and banded rainbows. We caught one in time to keep him from becoming breakfast, and kept him in a pen for about three months. Now he is about 1.5 inches long and has been released to live with the others. Truly amazing. Guess we must have lived in places where tap water had medium hardness as we had never run into this issue and had never tested tanks for GH before. Glad we know what to do now. Seachem Equilibrium is our friend. If you have a similar need, we highly recommend it.

## Questions & Answers

**Q: does Equilibrium may cause green algae growth? i dose this product very precisely in my RO water, but green hair algae is out of control. Thanks!**
A: At 4 months, the aquarium is early in its stabilization process, lots of things can contribute to algae growth: nutrient leaching from substrate, rocks, decorative wood, etc.  Also, in in the small water volume of a 12 gallon tank it's very easy for excess nutrients to build up quickly.A few thoughts:Feed your fish less.  They need less food than you might think, and a nutrient-rich diet means extra nutrients in the waste.  Excess phosphate (as well as excess nitrate) is the byproduct of excess feeding.  If you cut the feed quantity in half, it would be a long time before your fish showed any signs of malnutrition, if ever.Feed your plants less.  In fact, you may consider stopping any fertilization until the plants show signs of deficiency.  'Higher order' plants will out-compete algae for nutrients, but if there's plenty to go around, algae will win.Algae love red light.  Many folks with florescent light systems note an increase in algae growth as their tubes age and shift toward the red end of the spectrum.  Adding red light aids and abets the algae jailbreak.  Consider removing the red light input until the algae is under control.  Consider reducing the overall light exposure.  Maybe back off gradually to 4 hours a day.  Also, shield the tank from any strong natural light exposure.I'm a big fan of Purigen and Matrix.  I'm sure Renew is a fine product too, though I don't have any experience with it.  In general, the filter media will remove a good portion of the excess nutrients from the water column - but not as fast as algae will.  Reduce the nutrient input in the first place and there will be less the filter has to do.  Weekly water change is good.  Consider stepping up the substrate vacuuming to weekly as well.  Also, if you have a sponge in your Aquaclear (I like those filters) rinse it out in the tank water that you withdraw on a weekly basis.     Patience will be key - nothing happens fast in aquariums except disasters.  By reducing nutrients and favored light spectrum, algae will eventually subside.  (A personal opinion)  Don't be tempted to use any of the 'instant algae remover' products - they are herbicides that may or may not harm your plants, beneficial biota, and fish; but are toxins, and will not rid you of algae, only the current crop.  Long term, nutrient control is the solution.

**Q: My tanks are already established, Can I add this to an established tank?**
A: Yes, it has many micro trace elements.  I use RO water (Reverse Osmosis) for my aquarium and this product returns those missing elements and compounds that are needed.  But these do not support rampant growth of algae.

**Q: How does this do for shrimp?  I have a heavily planted tank but there are shrimp in there.**
A: Bamboo shrimp and filter feeders are the only ones sensitive to this.

**Q: How will this affect the fish? Will this affect the same way like Seachem Replenish?**
A: It does affect the fish since it raises the general hardness (GH) of the water. Make sure you keep the hardness at a level where both your fish and plants are happy. The exact level varies, depending on what type of fish and plants you have. But most will do well at around 5-8 degrees general hardness (dGH).  Also, never raise the hardness too quickly, otherwise your fish will get osmotic shock. After you raise it to the right level, you want to keep it stable by adding enough after each water change, like the directions say. The amount will depend on how hard your water is to begin with.

### ⭐⭐⭐⭐⭐ Great product for minerals
*by T***N on January 14, 2026*

Great for adding the minerals that my RO takes out of the water

### ⭐⭐⭐⭐⭐ Saved my Java Ferns with black spots.
*by Y***. on April 20, 2025*

I have a lot of Java Ferns that grew big with help of CO2. After I stopped pumping CO2, they started developing black spots on their leaves and pretty much dying. I didn’t want to go back to CO2 system, and wanted to keep my tank low tech. So, I tried many alternatives like liquid CO2, various ferts, nothing helped. This product did! Used it once, then in 2 weeks my Java Ferns started growing like I resumed my CO2 injections. I keep adding it with each water change, plants love it.
