Good for shrimp!
Our water is a little on the soft side, and we love our shrimpies, so we use this product to maintain a comfortable hardness level for them in developing their exoskeletons. It's easy to use, not messy, and works on its own when used as directed, so there's no need to keep adding a little more. We drop it into some dechlorinated, treated water during routine water changes so it can dissolve before hitting the aquarium. It has made our lives easier and our shrimp are strong and healthy!

Really like it
Seachem Equilibrium is a must-have for anyone using RO or distilled water in a planted tank. I use RO water for my nano setup, and without remineralizing, my GH drops too low, which causes issues with plant growth and snails health. Equilibrium solves that perfectly. It’s easy to dose, mixes well, and provides essential minerals like calcium, magnesium, and potassium all critical for healthy plant growth and osmoregulation in fish and inverts. I’ve noticed a big improvement in leaf color, strength, and overall plant vitality since I started using it. It doesn’t affect KH, so if you’re targeting soft, acidic conditions but still want stable GH, this is perfect. I like to pair it with Seachem’s alkaline buffer. Highly recommend it for planted tanks, especially if you’re using RO/DI water or dealing with soft tap water. It’s a game changer for maintaining a healthy aquatic environment.

Perfect Hardness!
I’ve tried baking soda to raise my hardness but it also raises the ph and then I have to use ph down to offset it. It never really worked that well and it’s a headache to do (it does well for kh though, just make sure you have ph down on hand). Equilibrium works PERFECTLY in raising my hardness and not affecting the ph. I also think it saved my snails! My snails never moved and I thought they might be dying. I did some research and read articles that mentioned snails will hardly come out of their shells if the water conditions are not right. They need minerals for their shell health. My snails are out cleaning my tank ALL THE TIME now that I’ve put this stuff in my water! This really is amazing stuff!
