So ive got a 55G SW tank setup and have recently purchased a skimmer. It can be placed in sump or has a HOB kit. Ive got it HOB b/c i dont have a sump. Well the pump for this thing is HUGE and i hate the way it stands out in the tank. I has wonderin if i could turn this rubbermaid bin i have (31G) into a sump that i could simply place the skimmer and thermo in. What would be the best way to go about starting this? I know you have to have a return pump and some kinda of overflow. What size pump am i lookin on having to get. Also what would be a safe guard for this method during a power outage? Im noob at the whole sump idea.
