I currently have a hang on back filter Aquaclear 400. I am thinking about switching to some type of Refugium to lower my nitrates. I am haveing a hard time keeping them below 20 ppm. I was wondering if a hang on back Refugium would work? Or if I should just do a Refugium under the tank. Its just that the plumbing is pretty intemidating to me. I had a wet dry filter before and I was very unhappy with all the noise and plumbing issues, thanks for any help!
