How Much UV Light Do Corals Need?

Can algae grow under blue light?

Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria.

Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals..

Does red light promote algae growth?

Algae uses red light to conduct photo synthesis. This scientific fact can be used to limit algae growth. Using only a little red light will slow algae growth. The less you use, the slower algae can grow.

Do Zoanthids like high light?
