The instructions for this stuff are a little vague to me. I'm going to use it to get a quarantine tank going. At what point can I add the fish after putting in the Bio spiro? And where do you put the stuff? Onto the filter cartridge or just pour it into the tank? One more question...should I remove the charcoal from the cartridge?
Any answers would be appreciated! Thanks!
