Blue light?

Recommended Posts

Do aquarium plants receive any benifit from blue light? I’ve read that algae really likes it.


I am a new tank owner with a pretty fresh tank that I am working on getting balanced. I have some great algae and black algae popping up, but I don’t thinks it’s a problem (yet). But am just wondering if a guy even bothers with having the blue light on.

Try not to focus in on which color, just understand that too much light is an algae trigger. I run my light for 11 hours and 1% blue for an additional 4.5 hours. 

I drop overall light intensity to compensate, and this tank has very little light demanding plants.
