Ocean Art NO3+

Without NO3 and PO4, a marine aquarium, especially the corals, cannot grow well or regain color.

This also applies to plants in a freshwater aquarium.

These nutrients are also indispensable in an aquarium's ecosystem.

ReefELIXER, ReefFUEL, ReefBALANCE, and FreshwaterELIXER are products that lower your no3 and po4.

But if it is too low then you can use ReefFUEL no3 + & po4 + to increase it.
