A friend of mine got this stuff for his new tank (a 45 gallon long). Are you supposed to use a filter cartridge while using this? Cause my friend isn't (He was afraid the cartridge would pull it out of the water) and He is on his 3rd day now and there is this brownish slime on his tank's walls. He has bio wheels in his filters but no cartridges and there is no decor in the tank either. The substrate is play sand. Do you think the slime is the BB because it cannot anchor itself to anything? Its the only thing i could think of.
P.S. - I dont know if this is relevant, but he added stress zyme to his tank as well, I believe on the first day. And he has 6 goldfish in it right now, for the purpose of cycling.
