Ok I've read the directions, I can build a house but how the heck does this thing work? I want to put it in my sump. What do you do with the return? Whats the blue sponge cylinder for? How deep does it sit in the sump/refuge? Will the sand in the refuge hamper it? Does the cup just sit on top??? GRRRRRRR this thing has me confused.
