Hi,

I wouldn't be too laid back on this one. Personally, I've have had tanks
that have been slightly off level before without any ill effects. The only
failure I've experienced was a slow-ish leak from an older, second-hand tank
that still caused a fair amount of damage. I think that one was due to
older, dried-out silicone.

However, I've been advised by my LFS owner (who is very experienced in the
trade) that, apparently when the tank isn't perfectly level, the angles and
difference in weight places more stress against some of the planes of glass
and joints than others. It shouldn't affect a well-built stand, but in some
cases, the unequal weight/force can cause the tank itself to fail, which can
be catastrophic.

Based on this, in the long term I intend to shim up my 90 gallon setup,
which is slightly off level at the moment. It'll be a nasty task and I hope
to get it done by draining most of the tank and enlisting a few strong
friends to help lift the tank and stand without actually doing a full
tear-down. The floor itself should be strong as it's close to the center
beam of the house and spans several joists, but the lack of being level
concerns me, and it's not a risk I'm interested in seeing the down side of!

I know: typical second-hand internet advice, so take it FWIW... ;-)

i just moved my 125 gallon fish tank (not fun) into my sunroom. after
the
water was in, i noticed the water is about a half inch higher on one
side than
the other, and i took a level and found out the sunroom is not quite
level. my
first question is will this imperfection jeopardize the structure of the
tank/stand? i dont want 125 gallons of water in the sunroom! i can live
with
the imperfection if it doesnt mess anything up

also, short of draining the tank and puting something down to prop up
one end,
is there any other way to make the tank level? thanks

I think your tank is fine. At a previous residence I had floors that
were not level, and it didn't bother the aquariums for the 5-1/2 years
we had them set up there. --Mark
