For those that use residential Compact Fluorescent bulbs over their refugiums how long do you go between changes. My chaeto growth has crawled to a halt so I am wondering if I need to change out the bulb. It is around 10 months old.

Never mind - just went out and bought a new one - see if it makes a difference. Life of the bulb is supposed to be 8000 hours. I figure I'm sub 4000 but if $15 makes a difference it is money very well spent.
