Light advice please - after my current tank sprang a leak I have ordered an aqua marin 900 - measurements are 90cmL x 50cmW x 53cmD (35" x 19.5" x 21"). I have been running a single AI Prime 16HD on my 60cmW x 35cmW x 40cmD (24" x 14" x 16"0 with no issues - apart from the fish I have only softies (mushrooms, kenya trees, palys, gorgonian fans, cabbage and xenia) which are all thriving and growing. Will I need to add an addional AI Prime or can I get away with continuing with my single unit? Now that I wil be getting a sump I need to add a return pump and larger skimmer so I'm trying to keep the cost down!
