Put a real light on it and you will see what I mean. I originally did the same with the cheap clip on light from HD. It grew my macros, but nothing like they grow with my 65w PC light. I'd say the growth rate has at least doubled. Light penetrates deeper-my macros at the bottom don't die now, and it does not throw off the near the amount of heat the clip on light did. Most people who are really serious about their algae scrubbers usually put a MH on it for max growth.
