I had to empty the tank last night. I had a book that recommended putting pennies under the tank to level it out so I put a half inch worth of pennies under it and filled er up. Nice and level. Then I thought to myself, "looks kinda risky having all those rocks on there with nothing supporting the middle of the tank." I googled it and found lots of advice recommending NOT to shim the tank but to shim the stand. So I had to empty it all into a bunch of rubbermaid trash bins (because the water took forever to heat up to 70F so far) then removed the coins, put the styrofoam back and shimmed the stand. Lots of un-needed work if I had done it right the first time. Ah well live n learn.
So here's a picture of the setup:
and here's a shot of the room with the tanks in it:
