Bought your lights/fixture/bulbs new?? My guess would be time to replace bulbs. Or did you adjust your lighting schedule. Or maybe you should evaluate your possible calcium/mag levels. Like did you change your PWC
schedule which would affect mineral levels or change water sources or salt brands? There's a product called Purple Up to promote Coralline growth. Good luck!
