styrofoam and tank leveling

Probably not. BTW, styrofoam is a trade name owned by DOW chemical. The
stuff is generically called polystyrene, and it comes in 2 popular
formats, expanded and extruded, and in various colours. If your pink
basement insulation is smooth to the touch (not composed of many small
bubbles) then it's the extruded type. This works better for very large
aquariums (150g+), but really does not compress much for smaller tanks
(100g). If you have protrusions in your stand's surface (ie: screw
heads) and the stand is otherwise parallel to your tank (known as
flatness), then the extruded polystyrene will work fine. If you have
gaps between the tank and stand, then you want something more malleable,
like the expanded polystyrene.

Note that depending on where the loss of flatness occurs, the effect can
be insignificant to disastrous. If one of your tank's corners is in the
air, this is a bad condition (when filled with water, the side silicone
will be sheer-stressed). If the gap is along the front (or back), away
from the corners, then it's probably much less significant, as many tanks
will be fine with only corner supports. hth

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

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?


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

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.

Wow!! thanks. You sure know alot about styrofoam. My tank is a
little off at the corner, so I think I should use some foam...I guess
the expanded type.

thanks again.

I can't remember what it's called, but I used some stuff that I think was
insulation for between doors and frames. It's foamy tape-backed rubber(?)
that comes in rolls, and you can get it in different widths. I think I used
1" wide 1/2" thick strips between the frame of my 150 and its metal stand.
Worked great. HTH.
