Just got my new Nicrew Full Spectrum Light in the mail for my refugium/sump. I have a small question if this light is powerful enough to grow chaeto/macro algae. It says its made to grow plants in aquariums but not sure about chaeto. It has whites, blues, reds, and a green leds. Any thoughts?
Like above stated pretty much all lights can grow it just some do it alot better than others, specifically those in the 660-460nm range. Your white leds contain those ranges just far less than dedicated lights with those specific diodes. Hence why most people's sumps look violet, lots of reds and blues.
