Picked up this PAR38 grow bulb. Spectrum looks about right for algae growth. 75W equivalent so not the strongest but it will be paired with a CAT CT3530 LED work light with an output equivalent of 150W.
 Using and old light fixture....  Came up with this genius!  Placed the CAT work light in front of the sump to get light at different angles and threw in come chaetomorpha.
