Hey everybody, I was wondering if anyone could help me determine what size sponge filter to get. I have a 36G bowfront and it already has an AcuaClear 50 hob. I was checking out AqAdvisor and it said I should increase the filtration when I added more fish to the tank. At the moment I have 2 small angels, 6 false julii corys, 2 nerite snails. I want to add 6 or 7 rummy nose tetras but would like to add a sponge filter to assist with the filtration capacity. Any ideas on which size I should purchase?
