What do you guys think 75 gallon reef running on 160 Watt LED Fixture. 20 gallon sump. 70 lbs of rock. Lot of Coral. Fish: White Bristle-tooth Tang, Yellow Tang, Blue Hippo Tang(Holding for friend while he upgrades), Coral Beauty, 2" copper-banded butterfly, 2 ocellaris clowns, orchid dottyback, and neon cleaner goby. I made the cover for sump intake look like rock with pond foam and epoxied sand, it worked out great everything is fine and it has coraline all over it. This tank is 4 months old. Any Comments or suggestions.View attachment 13256
