It's a "standard" 55g, so most likely made from tempered glass... so... I think I'm just going to build a new (acrylic) tank for this saltwater project ...
Planning a 24" x 48" tank at this point... 120 gal
I figure if I'm gonna do this, I might as well do it "right" !
Found a local source for cast acrylic sheet today... so I guess I need to make a decision on the tank size and get that ordered!
...still trying to decide if i want to build a custom sump as well, or just use the 55 for that.
(Always open to comments and suggestions... I like new ideas and correcting my own misconceptions.)
