I seem to be getting some mixed information on length of the photo period. I run 4 110watt VHO's with an icecap 660 ballest. It's a 55 gal. It comes on at 2:00 pm and off at 3:00am. It does get a small bit of non-direct sun light before 2:00pm. The lps, sps, and softies are growing at a fairly steady rate. I do however get a thin coating of
green algae on the glass, that requires scrubbing about once a week. Some have said at 8 watts per gallon vho intensity I should run the lights 9 to 10 hours a day instead of 13. Would cutting down the photo period be benificial to the tank? Would this cause stress to the corals and fish, who are very used to a 13 hour day? The algae is not bad or anything,but if I'm giving these guy's to much light and it would actually be better for the reef to cut it down, I will. Anyone's take on vho photo period would be great to hear. The more experience we can build off the better decisions we can make. Thank you all!
