Aquarium CO2 Regulator Mini Dual Gauge Display Bubble Counter and Check Valve w/Solenoid 110V Fits Standard US Tanks - LP150 PSI - HP2000 PSI Accurate & Easy to Adjust with Tools (Silver)

Great co2 regulator. Works perfect on a timer for my planted tank. I was worried because of the low cost but it works with no issues. My plants have exploded. Buy this with no worry, high quality solid build.

All the other CO2 regulators sold on Amazon are essentially the same. So rather than spend $50-70, I'll support this one at $30.I tested for leaks, no leaks.Yes the solenoid gets hot, hot enough where you can't hold it for too long but so do the other regulators - because it's the same solenoid.The needle valve is very good as-in the adjustment stays put 1 bps doesn't become 0 bps OR 2 bps becomes 5.This is better than the $100 aquatek regulator I have where both those scenarios above happened.I've been running it for a week so far and will update this review as we go long term.

The last gauge I was using went bad, and I've replaced it with this one. So far it was worked great, only time will tell if it will last a long time.

It is not accurate. On this regulator 0 psi = 17 psi. I had it as a back up Unfortunately I did not put it on a CO2 tank until after the return date.

Brewed my first batch and was looking for a CO2 regulator, after reading reviews on several other CO2 regulators. I decided to give this one a try and i was not disappointed. This was well made and cost less. Only thing to keep in mind is, it takes a bit of practice regulating the CO2 flow.

Broke on first use. Do not buy.
