    Excellent system for nano tank

    Posted by Jessica M. on 2nd Apr 2021

    Prior to purchasing this system I was using a basic starter kit (Fluval 45g kit) for my 3 gallon. This system, especially due to the solenoid and separate valves has allowed for much better precision and daily fiddling to get the bubble count right. The flow is consistent and it's a set of and forget it system which has made things so much easier. My plants are loving it.

    Great Service & Great Products!

    Posted by Mikey-Mike Austria on 9th Oct 2020

    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

    Posted by Darrel Jankins on 28th Jan 2020

    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.

    Co2 cartridge regulator

    Posted by Wendy on 19th Jan 2020

    Dipping my toes into trying CO2 for planted tank, and ordered the co2 cartridge set-up to try out in a nano. Regulator solid, shiny :) and easy to adjust, and holds its count even at quite low rate. Arrived quickly, well packaged, with good instructions. All good with me, coming back in a few months for my next regulator investment.
