Burch, HAHA - YES, I did remember the foam! I almost didn't put the plywood under the foam - I was debating if I needed the foam AND plywood over the stand. But I ended up putting both down, figure it can't hurt.
Buddy, yeah, it's probably just under 1000 lbs empty. Ridiculous!
Today I got the sump and scrubber box to a place called "Hole Specialists" - and they didn't have the equipment to do it!! But they referred me to a machinist in this industrial park and he's going to drill it. Hopefully it doesn't crack!! Upgrading the 1 1/8" holes in the scrubber box to a 2 3/8" hole, so it can handle the flow of the mag 7. (will be a 1.5" drain now)
Then plumbing the basement water reservoir into the first floor, where a 2-stage auto top off valve will activate the basement mag7 to top off!
