1pc W21.8 Oulet Argon CO2 Gas Brass Pressure Regulator Mig Tig Welding Flow Meter Gauge

There's a very simple way of adding CO2 to aquariums that involves just sticking an inverted plastic bottle in the tank and letting the CO2 slowly diffuse into the water. When you have multiple tanks and don't want to spend a fortune on solenoid switched dual stage regulators and diffusers for each aquarium, then the bottle trick is very simple and very cheap. This regulator and a bit of tubing is all you need. No its very definitely not as good as a proper set up, but that little bit of extra CO2 is appreciated by the plants, and the natural diffusion means you don't have to stress about setting precise levels. At least I don't :)

Does what it says. However, money taken first and then late delivery. Hmm.

Needed this regulator and flow meter for mig 150 welder to use in gas mode. Fits directly to Pubgas CO2 bottle with spigot for welder connecter hose.

Broke within 3 or 4 uses Pay the extra get a decent one

Works perfect

Looks good. However, it’s not what it says. Not suitable for Argon bottles. You would need to change the stem and nut fitting to a 3/8BSP male fitting. More clarity on description is very much a necessity. Don’t get caught out

Came all intact Notting broken. Just need to test it
