so, i have some blue- green stuff in a tank, this tank also has black beard algae…

there are lots of videos out there showing the slime build up, sometimes quite thick…

mine is less slimy, like an algae layer on the rocks in the substrate… I don’t think I’m special , and mine is ok… I think it’s just an earlier “infection”… I have a few questions…

cleaning it up seems easy enough, would circulating the water through a UV light kill and of the CB that is loose in the water, before it redeposits???

I’ve heard that red lights are one of the causes… over this tank I have one of my 1st sun rise / sun set lights, and it begins and ends in reds, and is white most of the day… wondering if I refigure out how to program it, and turned off the reds, if that will help prevent reinfestation??? my newer lights come on with blues, and not reds… that should be better???

this is it today…

Blue light is worse for algae overgrowth compared to red light, but they both promote growth. Blue light has a higher frequency so it penetrates the water deeper towards the substrate.
