Quality matters

No more headaches from nasty finicky needle valves. Moving to a high end needle valve is an amazing feeling. It just works.

So far am very pleased

I received my regulator 2 weeks ago and must say I am very pleased so far. My old regulator had a crap needle valve and would dump CO2 into my tank sometimes. After installing this regulator and also getting a new co2 diffuser (I got a metal one since I broke the glass one when taking it out for a cleaning), my plants are looking quite happy and there is a steady stream of bubbles into the tank daily that I haven't really had to adjust. I will say an improvement to the design could be painting arrows on the dials to indicate which direction to turn the valves in- not gonna lie that confused me very much upon installation. Also, there was one day where I set the pressure for 40 ppm? and the next morning it was at 20 ppm. However, that could have been other factors and not the regulator's fault. Anyway, overall so far I am very glad I spent the money on this regulator! Also, GLA's customer service was helpful. __________________________ Reply: It was a pleasure helping you with your co2 system. When setting up its critical to always adjust your PSI with the solenoid activated in the off position. This will keep any upstream pressure from effecting physical adjustment of the psi gauge. Its a basic mistake we see made often. However no harm no foul because it can not damage anything. It only takes basic procedure know how and the rest is breezy. Thank you for your trust and support!
