The tough part is building the right size box for the pump. The box has to be big enough that the pump doesn't drain it faster than it can refill and small enough that it doesn't just remain full. I'd suggest searching the boards for a DIY on that particular skimmer.

Depending on the pump, I think Grant at Big Al's may be able to advise you on the size of box. Building it would be the easy part.
