I am refurbing a 150 gallon 48''x24''x30'' which I bought for an excellent price off ebay. I need some advice with setup.
1.) Currently it has a single inside overflow drain set up as a wet/dry filter with bio balls and a 1.5'' bulkhead 6'' from the bottom. I am thinking about taking out the bioballs and building a stockman standpipe. Question is with one 1.5'' bulkhead am I going to have enough turnover? How many gph does one usually drain? I understand that by converting to a standpipe design I take away noise but I also decrease draining gph due to the loss of water weight. Any ideas how fast a 1.5" would drain as a standpipe verses under the weight of appox. 12-16 inches of water.
2.) I am currently building a sump/refugium. I have most of the design figured out except the return plumbing. If I plan on using an appropriate external pump, should the drain in my return section be 1.5'' or 1''.
Hope my questions make sense.
