Hi RC! After months of reading around the forums I've finally decided to get a custom 30 gal sumpless glass cube built, and I have a question for you guys, should i choose tinted glass or black acrylic for the back wall that separates the filtration compartment? The guy who's building the tank said there would be almost no difference in cost, and if I choose glass the overflow height would be adjustable but since amost every tank in this style that I see has acrylic for the back wall i figured i better ask the experts. So what would you guys do?
