I have just commissioned my new 100gal 5ft tank after some hickups. Filtration is a built in sump as seen in the photo. I have 2 internal filters/powerheads, 2 x 200watt heaters, two regent airpumps, 3 x 4ft lights (1 daylight.1 blue and 1 pink). Will mature the water for a day or two to remove chlorine before adding 2 fish to help with biological start up. Hope you guys approve.
