Hi All - I am fighting dinos, cyano, and other forms of algae. In order to get ahead I would like to reduce my photoperiod as much as possible. How short can I go? I've done a few day black out and was thinking i keep the photoperiod for 4 hours per day for the next few weeks. Is 4 hours of light enough to keep SPS in decent health? My sps all get between 250-450 par.

Thanks!

Just light the SPS and hand the cyano and dinos some other way. You can harm the SPS if you tinker too much with their food source.
