Just wondering what everyone thinks about these lights i seen on ebay. Im new to this and just started a scrubber today. Im using 1/4" cement board in the horizontal position in my sump. Dont know if its going to work yet, and i will probably get alot of laughs about this, but im going to try it anyway. Its seems really porus and rough to hold the algae. Any advice would be appreciated. Heres the link to the lights i would like an apinion on thanks http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 3DWatching
