Greetings all, I'm in the process of turning my old 75 gallon cichlid tank into a reef tank with mostly soft corals. As of right now, I have a HOB filter but will be doing a custom refugium within a month or two. My question... 1. Water Flow: Right now, my HOB filter is 350GPH. I'm planning on picking up a few power heads to up my water flow so I can start cycling the tank and curing LR. Any recommendations or what is a good range of water flow for a soft coral dominant tank? Keep seeing between 20-40x tank volume. Can some one confirm? 2. Filtration: With a HOB filter, should I remove the filter cartridge sine the LR would be my main filtration and will help keep nitrates down and leave the boi-wheels in place? Thanks in advance.
