I'm running the same light on my 40 breeder. I use preset #3 and adjust the time to come on and off when I want. I have had good luck with SPS but I put them high up in the tank. Softies seem happy on the bottom so I'm thinking the PAR drops significantly with depth. I've added a T5 recently but only run it about 4 hrs per day. I don't dose anything and so far the corals are doing well. Set up about 1 year ago.
Thank you very much, I've never used this fixture. Is there an option to make it more blue without going all blue?
