scraped off the black paint over chamber 2 and used Velcro to fasten the 3.1 nanotuners 3 x 1w 6500k led light to the back of the tank. http://www.nanotuners.com/product_in...roducts_id=369
Adds no heat to tank and I get great macro algae growth.
how do you guys have it in there? just the light in the middle of the chaeto? seems like itd smother the light. i was thinking about using a clear solo cup. thatd keep the cup chaeto back so there would be more surface for the light to hit.
