Seachem Equilibrium
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.
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.

FAQ
Can Equilibrium be used with tap water that already has some minerals?
Yes, Equilibrium can be used with tap water that has low mineral content. It helps to raise the essential mineral levels, especially when the water is deficient in general hardness or carbonate hardness.
Does Equilibrium affect pH levels?
No, Equilibrium does not significantly affect pH levels. It primarily adjusts general hardness and supports carbonate hardness stability without altering pH.
Is Equilibrium safe for fish and invertebrates?
Yes, Equilibrium is safe for fish and invertebrates. It is formulated specifically for planted aquariums and does not contain sodium or chloride, which can be harmful in excess.

Trevor Campbell –
I’ve used Equilibrium in my planted tank for three months now. The plants are thriving, and the water stability has improved noticeably. No fish stress or algae blooms. Great for RO water setups.
Maria Burgess –
After switching from a product with sodium chloride, my tank became much more balanced. My anubias and java ferns are growing well. The water clarity and plant health have improved.
Dylan Turner –
Works well with DI water. I added it once a month and noticed better root development in my plants. Slight adjustment in water chemistry, but overall positive results.

My planted tank has been stable since using Equilibrium. No more sudden pH swings or plant die-offs. It’s a must-have for any planted aquarium using RO or DI water.
