[Well, not exactly BROKEN, just could be much better. I have a glass 55, regular tank, with two acrylic walls to separate inflow, fuge, and return. But the walls aren't high enough, to contain enough water for the return. Problem is, getting that tank out to be worked on is a real problem - the wood support for the stand has to be removed to get it out.
One of these days, when your "business" is slower, you gotta come see the "hamster trail" anyway...lol! Wish I had used 'crete instead, would have been easier. Anywho, let me know when you have time, I'm a work-from-home, and usually here.]
