After reading,and reading,and reading,and reading about LED scrubbers I have decided to just keep using my CFL's . From what I could tell it was going to cost me about 300 bucks to build proper LED fixtures, and even then nobody seems to be 100% sure about the proper color of the LED's. I feel I can upgrade my CFL system for a fraction of the cost. I would like the hear from people who have found CFL lamps that grow algae like crazy,,and other mods to get just a little more out of my scrubber.
