A solid and reliable bit of hardware.

I have a 45-P aquarium that could benefit from injected CO2. After all the days of shopping and research I concluded that GLA had the most suited option for my planted setup in the form of the Gro Paintball Regulator.

The unit came promptly in secure packaging and was very easy to put into use. Unlike standard tank regulators, the paintball regulator does not utilize the included nylon seal as the paintball tank already has a gasket. Very convenient.

Speaking of convenience, the included bubble counter/check valve and the solenoid make this unit very convenient as a nearly all-in-one CO2 regulator kit. The only real “task” to get CO2 running in the tank is finding a local supplier. (Hint: buy your tanks from the local supplier for potential discounts on refills)

Be sure to also get a CO2-purpose coil of tubing and either an in-tank or in-line diffuser.

Oh, and their customer service is by far the best I have experienced in all my years of online purchases. Quick to reply and helpful always.

Order with confidence.

Thank you!

What a breath of fresh air this paintball regulator has been. After having so many issues with other brands this regulator has been a dream. The main selling point for me was the fact that this model can be used on every type of cylinder the market has to offer. It fits paintball,CGA-320 and disposable types. I think GLA should put that in the item description. Had I not contacted them I would have never known this. It arrived just in time for my christmas party woot! Thanks a million GLA.
