Phosphate Minus by Tetra is a natural way to reduce the phosphate levels in freshwater aquariums reliably and gently.

Excess phosphate can cause the growth of unwanted algae and it’s advised phosphate levels should be kept at 2 mg/l or less. Phosphate Minus uses microorganisms which release natural active ingredients in a natural way which gently removes phosphate.

Dosing is easy and only requires 10ml of Phosphate Minus per 40 litres of aquarium water which removes up to 2mg/l of phosphate, dependent on its initial level. This can be repeated every 2 days until the desired level is reached.
