Excellent co2 regulator

I bought this regulator along side a GLA DS series co2 regulator. I use this one on a 10g tank that has a small cabinet space so I needed something compact. I was not totally sure what to expect when it arrived but I can say this co2 regulator has a really nice build quality. The needle valve was super easy to adjust, install was almost thoughtless. I had it installed in under 5 minutes. This co2 regulator was above and beyond my expectations. GLA service was second to none to boot.

I dont know much about aquarium co2 systems, this was my first. Its been a couple months since I had it and its been absolutely great. The only thing I do is refill the bubble counter and wipe clean regularly with plant based metal cleaner. Its just so pretty I cant help but to keep it looking so good. Its the nicest piece of aquarium equipment I own and it was only $150. Very happy with all my purchases from GLA.
