styrofoam and tank leveling

I'm about to set up my 75 gallon cichlid tank. I've heard that you
should put a piece of styrofoam under the tank to even things out when
it settles. My question is, how thick should this be? 1/2 inch, 1
inch?

Also, there's a centre brace on both the top and bottom of the tank.
Would I need to carve out a groove in the styrofoam so the centre
brace at the bottom could slide in? Not sure if the styrofoam could
break the brace or something under all that weight. The brace is
flush with the plastic bottom edge of the aquarium.

thanks in advance.

throw the styrofoam in the trash. If it is a glass tank you do not want
anything at all touching the bottom of the tank. The only support should be
the tank edge. As long as your stand has a fairly smooth top everything
will be fine.

Depending upon teh construction of the tank, of course, since some do
want support and some don't.

If it's a tank that needs support, leave a cut-out around teh brace -
the whole point is o avoid concentrating stress, and from the
description, it sounds like you'd have one at the brace if you just
put it down on a continuous layer of foam.

Thanks for the reply. The surface is pretty flat, but not perfect.
When I place the empty tank on the stand (home made), there's a little
bit more than a 1/16 of inch difference between the tank and the stand
(on one side). Is that good enough?

It's a perfecto tank. If I were to use styrofoam, what thickness should I use?

1/4 styrofoam should be sufficient then. Look for expanded polystyrene
(not extruded). You want the one made of little bubbles.

as long as it's not a large gap it will be ok. As long as 99% of the frame
is supported it should be fine. My 135 has about a 6" section that I can
slide a piece of paper between the full tank and stand, and it has been fine
for 16 years ;o)

Almost always true, but I have seen a tank that started to leak from a
its unsupported base after 20 years. The unsupported part was about 6
inch long. Glass bends into the gap if the sealer weakens. It is best
policy to arrange for 100% flat base support.

I was thinking about getting the pink styrofoam used to insulate
basements. Is that what you're talking about?

So do you recommend using the foam?
