View Full Version : Ridding algae: replace bulbs or wait?

01/16/2008, 11:59 AM
I am in the process of getting my algae under control. In respect to the lighting:

1) Do old PC bulbs cause algae growth? Or is this a myth?

2) Am I better off waiting until my algae growth subsides and THEN replace the bulbs, or go ahead and replace them now?
