| Re: Oerflow - return question that sounds good. I could be wrong bu I think it is 1200gph for a 1.5" hole. If it is, that would mean you will need a 4800gph return..... might take 2-3 pumps for that.

| Re: Oerflow - return question How big is your sump gonna be? That is alot of turnover for most sumps. Have you thought of doing a closed loop instead? They make big pumps that'll do that kind of turnover though. |

| Re: Oerflow - return question Yea, you are gonna want external pumps for that. I used an internal one for my small 55 and they make ALOT of heat. You would almost surely have heat problems if you used in water pumps. |
