Red Sea Peninsula 500 owners. I am just setting up and need inspiration and help! Two questions please: 1) I've followed the set-up instructions for the sump - see my pic. Any suggestions? I plan to use the back compartment (smaller side) behind the skimmer section for a refugium. I've read that some owners have made modifications, but I figure I'll start with the manufacturers set-up. Also 2) My LFS suggested I place my Gyre (XF350) in a vertical position on the side of the overflow weir. Most pics I've see is placed horizontal 3 or 4 inches below the surface of the water. Suggestions? My return pump is a Vectra 2. I plan to stock with easy fish and softies and LPS to start. My lights are AI Hydra 16 (3 of them). Does the setup look OK? Anything else I should absolutely need to have. Oh, and I do plan to have 1" - 2" of sand. Thanks!
