+1 with the others.

I have my 180G display with 105G refuge/sump in my bonus room against 2 outside walls... I even had a contractor look at it, as I was going to put a support in the garage for it, but he wouldn't! He said you don't need it.

After over 2 years, it hasn't moved... I often check the level of the system, but also note the ceiling in the garage, nothing has changed.

Thanks guys I start to feel better when I hear other people who have had no problems.

I guess i'll just do what i can and watch for any differance or sagging in the floor,and if so I will have to dismantle it and sell it,because taking care of fish and watching fish while doing the laundry in the cold basement doesnt appeal to me:biggrin:

Wow thats 285 gallons plus the weight of the tanks.That makes me feel the best yet....soon I shall be able to sleep at night. Thanks:biggrin:
