WYIN CO2 Aquarium Regulator, Big Dual Gauge Display with Check Valve CGA320 thread w/Solenoid 110V for fish tank, 1pc include

Product came well packaged, feels very solid. So far it has been performing flawlessly for about 2 months. One thing to note: working pressure is preset and cannot be changed. That dial looking thing is not a regulator. Bubble counter works just fine.

Great, love it. Precise adjustment and quiet solenoid valve.

Do not buy this product. I got it hooked up and functioning the forst day with no problems. This is not my first tank with pressurized C02 by any means. Next day woke up and found something had broke inside the regulator and it was running full blast into my tank. Unfortunately woke up 2 hours after it turned on. Wasted half a 5lb tank of C02. Not to mention everything was belly up. Dont go cheap if you have a larger aquarium you could be looking at hundreds of dollars in lost fish.

I very liked the regulator.

This is my second regulator I bought off of amazon. Every time I open my take the left gauge shoots past the far right red zone. Can this be fixed by me or does this need to be returned. I noticed in a customer picture that my gauges are complete opposite of theirs. Please inform me of what can be done. The unit works fine as of now but long term I’m a little worried.

Don't buy these. They never work longer than a month due to a cheap solenoid and when you go to return them it's a tricky process. Not to mention if you have plants like HC or other high C02 plants they could likely die if you don't order a new regulator before returning this one as the return/refund window for me was almost 2 months. WYIN IS A CRAP COMPANY.

After 1 year the high pressure gauge (0-3500) stopped working and was stuck on 0. Its unfortunate cause I loved everything about it. The construction seemed solid.

Works well for the short period of time that it worked. Had two units go out back to back on me. Either it's the quality of parts used or I just have bad luck. Going to try a different brand.
