Elevated phosphate drives unwanted algae growth and slows coral and calcareous algae growth - one study found phosphate above 0.05 mg/L cut calcareous algae growth by 90%. Since th e effects kick in at such a low threshold, an accurate, sensitive test matters. Sensitivity: detects as low as 0.015 mg/L within seconds Kit size: approximately 50 measurements To keep phosphate input down, rinse fish food in a sieve after thawing (a major phosphate source) and check activated carbon for phosphate content before use, since low-grade carbon can add phosphate rather than remove it. If levels run high, a liquid phosphate eliminator or granular phosphate media can bring it back down while also helping with silicate, organics, and heavy metals. Show more
