Hey guys, I am new to the saltwater world. I currently have 2 freshwater tanks and want to build a beautiful reef tank out of a 40 gallon breeder. I am building this tank on a budget and do not want to break the bank. I am currently interested in the Fiji cube 40 gallon insert but they are sold out everywhere, does anyone know if they will be in stock soon? Looking to alternate methods of filtration I could do a sump but I don’t want to drill my tank. Does anyone have any alternate filtration methods?
