I miss the impact of the big tank, which was cool, but with the small tank, it takes a lot less to make it look full and awesome. Plus it makes me make smarter decisions about live stock. Ive automated most of everything on the tank. The Kessil Tuna Blue A80 is run by there controller and the top off is handled by the Smart ATO Micro, which is awesome. The ATO was a must, so much evaporation on these little tanks. I am super impressed by the Kessil lights also. Will be using another one when I start my 25 gal Lagoon tank
