converting a 55 to sump. fuge side will have on pc 1/4" glass for baffel and skimmer side will have three baffels for bubble trap. Question is, if I use 1/4" on the first one, can I get away with 1/8" on the second and third??
I'd go with 3/16 at the least. 1/8 is too thin IMO. you'll be working in the tank, and sooner or later bang something into it. If it was 1/8" I'd break it with my luck.
