Awesome tank. Cant see the gyre in there but loving sea whips and great polyp extension on your lps. Unusual to see an apex on a tank this size, how are you finding it ?Just added an xf230 to my 54g Corner Bowfront (I also have a EcoTech mp10) and it's added a nice additional flow to my tank. No issues with noise. I switched out one of the blades so I can run it in alternating gyre mode and I'm only running it at 20% and it's plenty of flow for my LPS.
