I know my cyanabacteria decreases, because when I turned my
lights on this morning, I thought it was gone. Then within a few
hours it was back. The green hair algae is about the same. Would it help any if I took one of the new light bulbs out and put
the old one back in? If so, what time period should I wait to put the other new light bulb in? The new light bulbs have been in since Wednesday.
