Single piece glass aquarium

[Socast]

A cylinder tank might be better suited for that depth having no seams.

That depth is perfectly doable.. my DIY wood and acrylic tank holds at 6ft deep with no issues. Its at 4.5 feet now though only because my background was only that high and I didn't want to buy another $700 panel to cover just a foot or so.

Where I want to put the tank means a cylinder isn't really practical, it's tempting to get a bowed piece of glass/acrylic not sure if that will help with strength but it will allow more space in the tank. I'd be worried about distortion though

If you go with acrylic you don't have to worry about distortion. I would go with acrylic honestly. If you brace the bottom properly you will have less chance of a blow out. It will not look very nice but can be covered up
