250g Stand Help.....

[Jon]

Here is my last bit of paronoia before getting water into the tank and I'm hoping to get some reassurances that I'll be ok. Anyway it's been a long time coming my new 250g tank (96" x 24" x 25") and have now placed it onto what I thought was a very level stand is now showing a few gaps between it and the tank.

Anyway here is the tank (outside finish moulding not up yet)
Front

Back

and all along the back the tank sits snug on the 1/2" foam

However on the right front corner the foam is loose. About a 1/16" wiggle for about 8" in and about 4" back.

So I got some thin (0.0078") sheets of aluminum flashing and cut 6 layers to fill the area

Also have about a 6" length along the front toward the left that wiggles about 1/16" or less. So my question is should I have done this? Does 1/16" really matter? Will the foam compress? Will the aluminum corrode? Any comments. Thanks,

Well here is a little more feedback. I just got off the phone with Derek at Miracles (the tank mfg) and his comment was to remove the flashing and to not be concerned with the gaps. Specifically, if the gap is less then 3/32" it should disappear once I put water in the tank. He feels that this is the maximum amount of compression a 5/8" piece of "open cell" foam will compress under the load of a full tank. So given that my gaps are only about 1/16" or about 67% of his maximun, not to worry. If fact to prove it just he suggest doing a dry run and fill it about halfway with water and it should compress out.

Anyone else have a similar experience or see any compression when filling a tank or had some loose foam. Thanks,

Well just some more results. I did remove all the flashng and I did fill the tank completly with water and yes the foam did compress, but not quite enough. My gap on the one corner is now only 6" in by 1" back with a gap of about 1/64". Not much at all but a gap none the less. Should I be worried? The area is very small compaired to total footprint (96" x 24"). But..... Would really love to hear some feedback from a few people. Thanks,
