Collection: Nutrient Control & Media

Brightwell's nutrient management range for marine and reef aquariums, covering both ends of the problem: bottled bacteria blends and a carbon source on one side, nitrate and phosphate supplements for tanks running too lean on the other, plus a phosphate-removing liquid and a granular media. Sizes run from 60ml trial bottles up to 2 litre containers. Test before and after any change so you know which direction your nutrients are actually moving.
