Actinics and algae
About a month ago I changed my bulb layout in my fixtures. I used to have 2 power glo and 2 actinics. I changed them to 3 actinics and one purple/white bulb. I like the look of it but I notice an increase in algae. Especially hair algae and some green on my sand. My phosphates an nitrates seem fine but could it be the lights?
