First, I would like to thank trmiv for my "new" 90 gallon tank. The tank is equipped with 2 horizontal overflows, each with a 1" bulkhead exiting the back of the tank.
Drainage: I'm thinking of using 1.5" PVC for the drain pipe. Is 1.5" overkill for 2 x 1" bulkheads? Should both drain pipes come together in a "Y" then drain into the sump or should each overflow has its own pipe leading to the sump? I've seen other people use ball valves in their drain plumbing. What is the purpose of this? If you wanted to slow your drainage wouldn't you just slow the return?
Return: This is where I'm most torn.
Option 1, 1"-1.5" perimeter return closed loop manifold with 8-10 x 0.5" T's flowing to 0.5" loc-line spouts. This seems like a relatively inexpensive way to spread flow throughout the tank. There seems to be several debates as to the most effective way to set one up. Any advice/experience would be great.
Option 2, Ocean Motion 4-Way flowing to 0.75" loc-line spouts. Pricy, but worth it from what I've read.
Oh yeah, I forgot to mention I'll be plumbing through the wall into a 100 gallon stock tub sump. This will free up all of the space under the stand for electrical and plumbing. I would like to limit the amount of holes in the wall. Ideally, one hole for drain and one hole for return. If anyone has good examples (pictures) of through wall plumbing I would be greatly appreciative.
Once again, thanks in advance for your help!
