Questions about positioning a 45G tank

[SA]

Hi all,

I have a 45G tank in my living room running for few months now, my concern
is that because it is in the middle of the room span every time someone
walks by there is a slight vibration and I can see the water and the tank
shaking a bit. The other day I had couple of little kids visiting and as
they were running around the tank movement was ever greater. It almost
scared me for a while.

If I had to guesstimate I would say about 2/8th of an inch movement at the
top of the tank at the most. This is a 45G tall tank.

I suppose this is not the greatest thing to be happening for both the tank
and fish, but given that I don't have a concrete slab or a stiff corner in
the room that works well for positioning, how concern should I be for the
integrity of the tank? I know that it weights quite a bit, is all that
vibration/shaking jeopardizing the tank structurally? It is an All Glass
model if that helps.

Thank you all for any suggestions and insight.

Regards,

Steve

I have a 75 gallon glass tank and 3 dogs in a narrow room. The dogs
play and crash against the tank's stand, their tails bang against the
stand and shake the fish. The fish seem able to cope. As for the
water, my filters and air stone are continually churning the water.
The 4 inch gouramis chase each other and hit the top of the water from
time to time. I don't see a problem with the water movement.

If the tank sloshing is making you lose sleep, maybe think about
re-inforcing the floor right under the tank with some cinder blocks, maybe
something more permanent... Got a friend who does construction??? ask him to
give you a hand, or some advice...

If the floor joists are perpendicular to the tank, the bounce will tend
to be up & down, which is a lot safer than if the joists are parallel to
the tank, which can also add a forward/backward motion. Tall tanks in
the middle of a room make me nervous. Adding a post under the tank will
eliminate the up/down and should reduce forward/reverse to become
insignificant. No one can give you structural advice though. Seek
professional help if you don't trust your judgement.
