Now I am building a sump, what can i use to hold the media I am using a old 55g tank and a pump that will handle up to 1350gph. I have built the durso standpipe, on a 1/2" bulk head so the pump can handle what will be coming out of the tank. I was going to use some rubbermaid tubs to hold my media, but I dont know if this will work. can someone give me some guidance?
