Re: That old topic...I am replacing my Tank
One option that you can do, not sure if it was mentioned earlier, is have the new tank made about 1/4" shorter in heihgt. Grab an old 1" garden hose, slice it into two peices long ways. Use the garden hose close to the front, back and middle of the tank to lower it, leaving the garden hose under the tank. this should give you about 1/16" to 1/8" of gap under the tank. Weigh the tank down. When i did it it took about three of us standing on the edge of the tank. Pour the foam mix. CAUTION: as the foam begins to expand it will start to fill the 1/16" to 1/8" gap under the tank and tend to push it up, hence why you need to weigh it down. Normally the first couple of pours will do this but once the bottom foam had formed, the foam will work its way up, and not the tank. If done correctly, not allowing the tank to come up, you should end up with foam cushioning the bottom of the tank, which will help prevent cracking or breaking. Cut any excesss foam, and the excess hoses.
Cheers
