I have chaeto in a small refugium with a 36 watt grow light, the usual kind that looks very pink. Of the 12 leds 9 are red and 3 are blue.
I would like to grow some red algae in there and from what I understand they only use the blue light, red reflects so this seems obvious.
The question is, if I go to an all blue led of similar wattage will the chaeto still grow and how much activity might I be losing. I'd like to have some dragons tongue and red gracilaria in the fuge.
