After visiting another members fish room to pick up some fish, I am now in full fish room plan mode. It had an air pump and pvcvwith little valves screwed into it. Currently I have 14 tanks, with the exception of the 3 show tanks upstairs, they are all running AC hob's. In the next month I am going to take advantage of the $1 gal sale, buy an air pump, build some racks, and set up the fish room I want. I am going to have 4 75's, then a mix of 40 longs, 30s, 20's, 10's, etc. No way i want the expense of putting hob's on all the tanks. I have never used sponges. I could use some recommendations on brands, sizes, etc. also where to get those little valve that screw into the PVC pipes. Should I keep the 110's on the 75's for the water movement? Will the sponges keep the tanks clear like the hob's? Anything else I need to know?
Thanks in advance
