Hello. I have had my Sat + LED for a few months now. I made the mistake of keeping the light on full spectrum mode all day. (Anywhere from 12-14 hours.). As you can guess, I had a huge algal bloom. Water was completely green. Ended up purchasing a cheap UV sterilizer, keeping the light off when we weren't home, and setting the light to the cloudy day mode. My question is, which mode on the light is least conducive to algae growth? I would like to leave the light on for my plants, and only have full spectrum on for a few hours. Does anyone else have this light? If so, of all the settings, which is best to leave on or cycle through?
