My 12 gal long is on its way!!! I was curious what kind of small pressurized CO2 setups you guys and gals were using for these little tanks. I previously had a 260 gallon planted tank but nothing this small ever. I know I would like to have an electronic solenoid (work and college both full time) so I'm not always home to shut off/turn on when needed so lights and CO2 would need to be on timers. I have searched and found a few things. The 24oz paintball tanks have intrigued me with their compact design as I hope to keep this tank on a narrow cabinet that doesn't offer alot of storage.
