Recently picked up the hobby with over a million questions but I will keep them for myself to find out through trial and error. My main question is the size of this “used “ glass tempered tank I purchased that I will be attempting to run a LPS ONLY along with a few fish this reef tank.. it’s a 120 gallon display box with a 40 breeder sump.sadly the display box is tempered and I will not be able to drill.. Will I be able to pull out enough flow to with ahang on over flow box ? Or should I pitch the tank and buy acrylic ? Any suggestions are much much appreciative
