Any acrylic experts out there

woochi · Oct 12, 2014

So I have a Acrylic cube tank that I need to know how much I can open up the top on it to fit a custom rock tower I built.

Tank info
20" x 20" x 24" tall
1/2 inch cast acrylic
Current top opening is 10"x10"
Two smaller openings in back of tank to access overflow box

So to get the rock tower into the tank I would need to make the opening in the top a 13"x13,
I know the top is for support of the sides but couldn't I go bigger?
How wide of a Euro brace is needed for a tank of these dimensions?
Any help is appreciated

Try sending a pm over to the guys at synergy or elite aquatics. They should be able to help you out. You can even try melvesreef.

Defenatly not an expert, but I think I heard 2" is the norm all the way around the top.

Put a bar clamp on the outside of the tank, cut out what you need, then glue new pieces of acrylic back into place when your done, remove clamp, and your finished.
