Aquarium additives and reef supplements

Aquarium supplements serve different jobs: maintaining calcium and alkalinity, correcting a measured element shortage, or supporting a particular feeding or nutrient-management routine. Choose by the parameter or need you have identified rather than by the number of ingredients in a bottle.

Start with current measurements and actual water volume. Check whether your salt mix or existing dosing programme already supplies the same components, and distinguish concentrates from powders that require mixing. Regular testing makes it easier to adjust to changing coral growth without stacking overlapping additives.
