Tap water often contains heavy metals and sometimes chlorine which is harmful for fish and invertebrates. The water conditioner JBL Biotopol helps to bind heavy metals and to neutralise chlorine. The water conditioner needs about 15 minutes to take effect. Then add the aquarium starter JBL Denitrol which supplies the aquarium with the beneficial cleansing bacteria not initially present. Only with the help of cleansing bacteria can fish excrements be broken down effectively. That’s why the fish stock can be added directly after the use of JBL Denitrol.
