Have a new marineland 60 gal cube that somes with 2 holes drilled in the bottom corner. I'd like to use both for drains so that leaves me either drilling another hole within the confines of the overflow or drilling a return hole somewhere else. The tank is rimless so I won't be spoiling that by running the return over the top. So looking for opinions.
Drill in the existing overflow? My main concern is if there's enough room to do it safely. If I can, this is ideal.
Also thinking of drilling a return center back close to the top. Downside is no overflow box to "hide" the returns. Upside is there's no overflow box. As long as I drill a hole in the bottom of the return that sticks in the tank I shouldn't have to worry about a siphon drain when the return is off right? I can always put a background color on the back of the tank and help camo the return plumbing.
Also thought of a closed loop since I'd be drilling but not sure that's realistic for a 60 cube. I was planning on 2 MP10's for flow and I already have one. One upside to this would be no power heads inside or outside the tank.
Thoughts?
