OK.. so more specifics. I won the little Remora nano at the club meeting at AC. I am using it on my 75 as the other skimmer I had was a Jebo and really didnt do much good at all. it works better than the old one and I am getting a nice dark funk out of it, but I fear that it is really not doing what my tank needs it to. so the reason I am asking this is that I am thinking about selling the remora and going with one of the Coralife skimmers they have at AC, or getting something else of a different design. I have a very tough situation in that I only have 24" of height under my tank to mount the skimmer in the sump. adding one beside the tank is not an option as little hands could easily get to it.
really the goal of the question was to get the pro's and cons of the different types of designs. I like the way the Coralife looked as it was working at AC. Lots of turbulent froth in the chamber compared to the remora.
