Here are some pics of my 4 day old tank It is not finished. The lights are temp while I am finishing the canopy. They are a mixture of 20k and 10k 250w HQI. The tank has a 8500GPH closed loop and a 50 gallon sump with chiller. There is also a custom made 60 gallon frag tank on the system. A 100 gal fug is "prob" in the works
