I have the Marineland 36" LED's the bracket extends out to 48". It's only about 5" deep do I might put another one on there. A Tunze 9002 nano skimmer, two k-1's for circulation. Have a Coral Beauty, Two False Perc's and a Blue Damsel. A Sally Lght Foot, Pepp. Shrimp and about 10 Hermits. If I get another fixture I plan to have a row of Ric's in the sand near the front glass. Might get a yellow clown goby. I do a 5 gal W/C (17%) weekly. Thanks for the comments.
