Stand bowing

[blub_blub]

I bought specifically an aquarium stand. Pretty sure I assembled correctly. There is metal support bar under the top surface but the edges of the top surface sit a bit higher than the support bar so when I put water in tank, it sagged down till the middle rested on the support bar.

35” wide stand, 1/8” higher on each end than in the middle. Tank occupies middle 16”. Directly under left side of tank, no gap between top surface and support bar. Directly under right side of tank about 1-2mm gap.

I don’t anticipate any additional sagging as the metal support bar is pretty solid.

Is this amount acceptable for a rimless tank? It does have a self-leveling matt under it. Not sure how much that helps.

Heres a stock picture for better view of the structure.

That looks suspect to me, and I think would get worse over time without some sort of reinforcement.

I guess they expect aquarium to occupy the whole stand? This way it will be even pressure... I would reinforce definatelly, but I'm not a structural engineer... just my 2cents - reinforce...

Also it's not clear did you put an aquarium mat under tank?
