Ocean Art po4 remover is an effective and easy to use product. The concentration, 1 ml removes 0.02 ppm per 100 liters, makes it very easy to calculate the correct dosage.
It works immediately and provides precipitation. This must be removed from the aquarium.
Dispense in a high flow area, near a filter sock, power filter, fleece or roller filter and/or skimmer. If your glass becomes a little dull, the dosage should be reduced. We recommend removing no more than 0.1 ppm phosphate per day. It is possible to dilute it.
