Hi all, IM a new member and need some help. I have a 55 gallon tank, with a 170 gallon air pump with 4 outlets. Right now I only have a 12" Air stone and a dragon with small air done in is mouth hooked up to a 4 gang valve. The problem is my long stone will not completely bubble. I know my pump is huge for the tank so what gives??
