YES! I am using a 3 gallon Mr Aqua bowfront tank (almost the same thing), but I am waiting to pick up ADA Amazonia NEW, some HC, and probably a 12" Finnex Fugeray. But otherwise, you can see that I have the tank, CO2, and the regulator already. I plan to call this project something stupid like PICO-OVERKILL...it's going to be the most high tech pico ever hahahaha.
