Planning a tank for my office. Will be 60X24X30. My reef was an acrylic, corner overflows, sump, closed loop, which I am happy with, but want to do a glass tank this time around. Getting ready to order, but still unsure of asking for corner overflows or not. Will be a tank for discus (that I've had for almost a year in 50G grow bare bottom), Canister filtration. Will ask to see if they will paint back of the tank, so aesthetically may be just a couple of tubes over rim of the aquarium. no canopy planned. Any thoughts/ideas...Is this too mundane of an issue. Thanks very much in advance.
