High nitrate values cause algae growth in laquarium. In the event of a lack of CO2, there is the risk that nitrate will be reduced to extremely toxic nitrite for fish. 250 ml of Hobby Nitrat Killer eliminate in short -term leau, by exchange of Dions, up to 12,500 mg of nitrate and do not give them back to the laquarium.
