My tank a RS 350 is now up and running for about 6 months. I have a mixed reef with medium to heavy fish load. I have a Bubble Magnus Z5. However, I feel the need to upgrade it. Not that it’s not working, but can I do better? I want to stock the tank quite heavy and approach it as a heavy-in heavy-out type system. I don’t have high levels of Nitrate and phosphate being stable at 2ppm and 0.03ppm (hitting 0 on and off) respectively. On my shortlist: Reef Octo eSsence 130 or Classic 110S, Tunze DOC 9410 or Red Sea 600. Anybody have any experience with these options or do I not stand to gain much buy changing my current skimmer? The cup on the Z5 is a bit small and it tend to skim wet. Any other skimmers I might have overlooked?
