Have a110 gall reef. Struggling with hair algea. Maxspect p series led
lights. Strong skimmer. Using ro
water. Think I was over feeding. Pwc
every other week of 25 gall. Will start weekly of 15 gall. Do have corals and want to go dark for a while. How long can I leave the lights off and not hurt the corals. My lights are on the automatic setting and I am not sure howto shorten the span of the automatic setting. Love the lights but the settings and directions can be complicated.
