I am in the process of getting my fish room started. It will have around 14 to 18 tanks and around 1700 gallons or so. I have a lot of different questions regarding plumbing, air compressor, filtration, pumps, etc. Does anyone have a similar fish room set up in Southern California I could check out? Does anyone know of any businesses in Southern California that offers supplies and help to set up fish room plumbing? I have found similar business that do that but they are on the east coast. If I have a two pump system with one pump sucking water out and one pushing the water back to the tanks can't I just put a line of "in" and "out" pvc from the top of the tanks so I don't have to have predrilled tanks? Please help.
