I just built a fuge into a 20gal sump. The fuge area is around 12"X12" What would be a good small fixture to grow macro? Preferrably chaeto, maybe spag.macro? How many watts can fit into a small fixture? Ive seen a small fixture in a LFS that has (2) small 9watt bulbs. Would that do? Greatly appreciate any help.
