What effect does Pond Wizard have on nitrate and phosphate?
Pond Wizard removes the nitrate arising from the biological filter. Nitrate is formed from the conversion of nitrite that in turn has be oxidised from ammonia. Nitrate can be reduced to zero within a few days and kept at zero by the action of the microbes in Pond Wizard. Phosphate is also reduced but usually much more slowly. When the nitrate level in the pondwater is zero or very, very low there is no food available for the algae – either blanketweed or algae bloom.
