Something to worry about?

[LadfromLondon]

Evening all,

I have noticed warping in DIY concrete block stand. Nothing has been filled with water yet, so I presume this is from the the two central blocks on the second level, where there is no central support underneath. The only weight on this section will be food/equipment which can be seen, so virtually minimal weight.

From my understanding, the blocks directly beneath any aquarium are the ones which support the weight of the aquarium. Anything below is for aesthetics, i.e. adding height.

Do I need to take any actions to address or correct this before I go ahead and fill up?

Any suggestions or solutions? Maybe changing it from 3 blocks and 2 blocks in each section to 4 and 1?

It’s a 82G full Rimless tank above this section. The tank above is sitting on plywood and a thick mat. Do rimless tanks require central support, or is the support on the 4 corners of the tank sufficient?

I’d suggest laying the blocks flat rather than on the side. . . Should provide more support and stability.

The warping is likely from just the weight of the two central blocks on the second level. I'd suggest putting corresponding blocks on the bottom level also so there's direct support.

Those narrow blocks also cause me some concern about stability, but it looks like there's also a row along the back, which should help.
