Well I want to add 2 more tanks to my setup. One as a coral
frag tank and one as an invert breeding tank. All of them would be on the finished side of the basement in the previous arrangement, so athestics are somewhat important.
I may be able to pipe to the nonfinished side and go with an external pump setup with my display on the finished and the other 3 on the unfinished side. I don't know how you handle overflow in that situation as it would be about a 15 or 20' run horizontal of pipe. Getting the return back is easy, but how do you handle the overflow to the pump.
Nothing is ever simple. Thats why I like this hobby!
