I built a closed loop for my 90 gal. reef tank. I used a mag 9 submersible pump but I used it inline. I am not happy with the flow or the noise that my pump is making. I want to move up to a more powerful external pump. I only have softies so I don't need a lot of flow but I think I need at least 1200gph. my question is what pump (size and model) would give me the flow I need and low to no noise I'm looking for? If possible.
