Acrylic tank. Does the stand need a full flat table top?

[Magic mike]

I just got a 75 gallon tube tank. Pretty much two tanks connected in the middle with two 5in holes. It's acrylic and the stand that it's been on for the last 10 years has a stand with a open area in the middle.
I always thought acrylic tanks needed a whole flat table top, and not a top that just goes around the edges of the tank.
Thanks

When you say open area, do you mean in between the two where the tubes connect them or do you mean there is open space under the tank portions and the bottoms are not fully supported?

The quick answer is acrylic should be fully supported, if not it voids any warranty. Acrylic will flex and most likely sag if not supported completely. Check the bottoms for any deformations

Now if you mean that there is no support for the 5" that the tubes span, then you should be ok as long as everything is perfectly level. Any unevenness between the two sections will put stress on the tubes, so again better to have a stand that completely supports the bottom.
A piece of 1/2" plywood cut to size would solve it.

most definitely, absolutely, without a doubt stick some plywood on that sucker and check the tank(s) for any signs of stress/deformation on the bottom panels.
maybe even add a brace in the center.

Will do. Off to Lowes.

Thanks!
