Ok I have a Red Sea Reefer 170 and I started it a few months ago. I went with the Current Orbit IC. I went with them because I wanted the Loop system they have to run my flow pump and my poerheads with everything elase. The tank was going to be a LPS and softy tank just like my BioCube 32 and I love everything about it. Lately I have been thinking of changing my lighting on it for a couple of reason. I would like to have lighting that can be ran by my Apex and something that is smaller over the top of my tank. I have been thinking as well to maybe having some SPS in this tank because of my BioCube already being full of the LPS and softies that I love. I have been thinking about the AI Hydra with the arm as well. Im pretty sure that one would be enough for my tank and with the new setting on the Apex can be ran wireless and not have to see the wires ran over the tank, which I really, really love. I would like to know what everyone else thinks and what everyone is running if they have a Reefer 170. I know, I know Kessil, Kessil, Kessil 360. I just want something different. Other then their shimmer I dont care for or about Kessil. I really feel their way over rated. Thanks everyone for you thoughts and ideas. P.S. Oh and which would you use the 26 or 52?
