I bought this to get rid of some smaller green algae that are developing on my stones. About three weeks after installation I developed stubborn reddish algae clinging to my glass and accessories. I didn't put two and two together until I recently turned it off and voila...my red algae never came back. I will remove this block and discard it from each of my tanks.
