sump help!!!!!!!!!!

I have found this bulb to work best.

Seconded! I use the same exact bulb and I get awesome growth on my chaeto.

I do not run my fuge light 24/7 because studies have shown that chaeto needs the rest cycle. My fuge light runs from 10:00pm till 11:00 am (directly opposite of my main lights to help stop PH swing).
