SeaChem Equilibrium For Planted Aquariums 300g
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.

FAQ
Can Equilibrium be used in a freshwater aquarium with no plants?
Yes, Equilibrium can be used in freshwater aquariums, but it is primarily formulated for planted tanks. In non-planted setups, it may still help stabilize water chemistry, but its benefits are most noticeable in environments where plants require balanced minerals.
How much Equilibrium should I add to my aquarium water?
The recommended dosage is typically 1 gram per 100 liters of water. Always follow the specific guidelines for your aquarium size and water source. Start with a small amount and monitor water parameters.
Does Equilibrium affect pH levels?
Equilibrium does not significantly alter pH levels. It primarily adjusts general hardness and supports carbonate hardness stability without affecting pH directly.

Phil Springer –
I’ve used Equilibrium in my planted tank for several months now. The plants have grown stronger and the water stability has improved. No signs of algae or plant stress. Works well with my RO water.
Melanie Hughes –
Good product for balancing minerals in RO water. My aquarium plants are thriving and the water parameters have been consistent. I added it once a month and it made a noticeable difference.
Jacob Sanderson –
After switching from tap water to RO, I was worried about mineral deficiency. Equilibrium solved that. My anubias and java ferns are growing well. Easy to mix and effective.
Sarah Dowd –
Used it in a 120-liter tank. The general hardness stabilized after a few weeks. No issues with plant health or water clarity. Would recommend for planted setups.
Donna Kelly –
Perfect for planted tanks with RO water. No sodium or chloride, which is crucial for sensitive plants. My tank looks healthier and the water feels more balanced.
