I'm running Chaeto in 2 nano's... a JBJ 12 and an Oceanic BC14.
Both are within the sump area, with white/royal LED's on the back of the glass (coating scraped off).
I'm running the lights when the main lights are off -- and have noticed significant and consistent Chaeto growth, less PH swing, and less GHA growth (down to near zero from very significant) -- which the GHA growth was why I started running the Chaeto in the first place.
