Hi all. I managed to pick up an Iwaki 800+ gph pump , used, for a trade of an AquaClear 300, used. :jumping: I was planning to use my 30 gallon for a sump but need to rethink the plumbing for the external pump. Question is, what would you all recommend for a HOT overflow. Local LFS is pushing CPR overflows, but I have heard some bad things about them. Are they any good? I would be looking at about 600 gph flow rate through the sump.
