Phosphate directly inhibits calcification by corals and coralline algae - even at low levels. The health of plants in freshwater aquaria will also be impaired by raised levels of phosphate in the water.
The optimum phosphate level - particularly for reef tanks - is often quoted as zero or 0.05 mg/L (ppm). Most chemical test kits will however find it very difficult to either detect or give accurate readings at these low levels.
With its ability to register the presence of phosphate in salt and fresh water at extremely low levels, the new Hanna Phosphate Checker offers a real 'must-have' addition to the fish lover's equipment chest.
