Great Service & Great Products!

Sent an inquiry thru the website abt this & got an immediate response. Been out of the hobby awhile & my q?s weren’t dismissed. Thank u. As for the CO2 system— the value is hard to beat, the solenoid alone pays for Itself. The whole unit works wonderfully & there r very detailed instructions included. All you need is CO2 Tubing, a Check Valve & a Diffuser & you’re all set! I bought the replacement CO2 cartridges but an adapter they sell here can make it fit onto larger tanks /if preferred.

Absolutely perfect

You will not find a better nano co2 kit on the planet. This is the best Nano co2 kit I have found anywhere. Not even ADA kit can compare to this in price,form and function. When this arrived I was truly blown away at its build quality. Its heavy duty and means business. The guys at GLA have been doing co2 systems since 2006, they know what they are doing. This nano kit comes totally complete and has been working flawless in my 5.5g nano tank for a few months now without issue. The only thing I have to do is refill the bubble counter. Which by the way, you have the option to run an inline bubble counter. You dont have to use the supplied co2 bubble counter. You can attach tubing directly to the needle valve, it comes ready to go. Look no further, this is THE nano co2 kit.
