In my previous thread I said I was going to set up my new tank on the particle board stand that I already had, but I got too paranoid and ordered a steel tank anyway (lol). I love the way it looks and it has a powder-coat finish, which saves me the trouble of waterproofing it, but the top edges aren’t flush with the rim at all. I’ve read plenty of opinions on whether or not foam is good to use on a rimmed tank—some say it can’t hurt, others say it’ll just add to the pressure points. I’ve also heard that a rimmed tank only needs to be supported at the four corners only, not the whole perimeter, and others have said that this isn’t true. If I go to buy foam, is there a specific foam, type and thickness, I should look for? Should I only put the foam on the perimeter in that case or cover the entire bottom? Thanks in advance for the help!
