wanna put a drain in the white thing to wash away the salt creep?I bought mine used at a steal. Already drilled so that's why I ran plumbing the way I did and had modular marine custom make some overflows. I would have preferred one 72" overflow with returns coming in on the outsides of it but I had to work with what was there. The guy I got it from never set it up and bought it in tampa...no idea who made it...its beastly though.
