Waterbox tank glass bowing

[Rickybobby]

Hey everyone so last week installed a new red sea diy mesh lid kit on my tank and when installed the lid looked like it was pulling tight so we redid it. It was better yes. Today I looked down the glass and sure enough after 1 years 3 months the front glass is blowing. 4 foot straight edge confirmed. Anyone else see this??

Is the actual glass bowing or is tank out of square?

All larger rimless tanks do this. It has in all likelihood been that way since you filled it the first time and wasn’t noticed. Freaked me out the first time I saw it in mine.

Update. Called Waterbox. He told me the rimless tank would do this. Ok. It’s cool. Just scared me the tank is perfectly level on all directions
