I had already made a post about this aquarium and my concerns about there being no bracing and the plastic bracing all being separate pieces.
I was told that this aquarium would be strong and that I have nothing to worry about.
I decided to go ahead with this build. The aquarium sits on a leveled Alufab aquarium stand with a 1/2" piece of HDPE under the bottom trim
I finally filled the aquarium up and at the top I am getting almost a 3/8" inch bow across the 48" panels.
Should I just cut my losses and sell this aquarium?

I feel a little concerned that there's not a center brace on the stand itself. Was that the stand supplied by Planet Aquarium? If it was, I would trust their judgement over mine, but if not...

I have a mega matrix 300 and it is a tank. I’d trust their construction.
I contacted planet aquariums and the bowing was within spec. 1875" per side and they allow up the .25"
The 120 unfortunately doesn't have any euro bracing or cross braces like the 300 does.
My 120 most likely would have been fine for many years but now I'll be able to sleep better with the glass cross brace.

I would worry about your floor going before I would worry about that tank or stand going.

We use Planet almost exclusively. While we have an account with Glass Cages and think they make outstanding aquariums, we have total trust in Planet at this point.

120 with glass cross brace installed.
I started with a non-drilled mega matrix 120 and drilled it myself to fit a Modular Marine overflow.
Note to anyone else wanting to do this; make sure to order a mega matrix without the black background. The heat used during their coating process partially tempers the back panel of glass.
This is another reason I feel more comfortable with he cross brace due to the tank being modified.

I just got this same tank, and with shipping it was right at $1800. I see that you are in Texas, so you might be able to just go pick it up and save $400

It stopped the bowing and the front panel is completely flat when checking it with a level. I am very happy with how it turned out.
It probably wasn't necessary but I feel better about it now.
I paid around 1600 shipped to Southern Michigan from aquarium specialty. This was with all standard glass panels, no painted background and no overflow box.

Glad to hear everything worked out.👍

Yeah I heard shipping a tank can be expensive so i might just drive the 9hrs to Dallas and pick it up myself.if I still lived in Houston it wouldn't be all that bad but i move down by the border near south padre island.it will probably be a two day trip at the least.
