I wish I could come, but we already have plans to shop for a house this weekend.
No worries, it's the thought that counts mostly.
Good luck on the house hunting!! BUYER'S market...wish I was in it to buy.
I wanted to check to see if you spoke with a structural engineer about the weight of the tanks? I'm almost certain that the FOWLR will need extra support in the basement. The 110G might be fine because it looks like it is beside a weight bearing wall and probably sitting across 3 beams. The FOWLER on the other hand looks like it will be sitting on 2 beams (if your lucky) and running out to the middle of the beam. There is probably metal beam running from where the support wall ends under the 110G to the other end of the house (probably the kitchen) which is the other side of the beams the FOWLR will sit on. These beams need to be reinforced.
You should check this before you start filling the tanks with water.
BTW. The way the beams run is just speculation based on the pictures you gave us. It is possible that there is a metal support beam under where you are placing the FOWLR which would be more than enough to hold the weight of the FOWLR, but then the 110 would be next to a support wall with half it's weight in the middle of a beam and should be reinforced.
