Glass aquarium support

[ddaquaria]

I have a 6-ft 220-gallon GLASS aquarium. It came with drilled holes in the two corners for filtration using overflows. I recently added two more holes that are almost centered and 2 feet from each side (creating a closed loop). My stand is an open making the bracing supported by its edges, but only the bracing is supported. Do I need to worry about supporting the glass now that it’s drilled in the center? The glass is about 3/4” thick.

On a glass tank that large I'd want additional support on the bottom center regardless of how many holes drilled.

Thanks for the feedback. Definitely helps with my original concerns.
