just 1 more tank ok honey

Ive got a 180 with a 40 gallon sump on my floor. as long as you are spanning the joists and on a load bering wall you should be fine. i wouldnt put it in the middle of a room though.

I have a 90 with a 30 gal sump and am not spanning any joists at all. Running parallel and not over a loadbearing wall either. Been like that for 2 years now with no problems.

i have 160 total over 4.5' and i am hitting about 4 joists (one is doubled) on a load bearing wall. BUT there was a jack in the basement about halfway in from the wall(where teh tank sits) that helps out and is underneath the double joist...if that made any sense at all!
