  • Impressive unit
Size: Pro-Se
First thing's first! This is an American model (thread pitch matters) and doesn't require any additional gaskets (which you may notice in older reviews). This has an o-ring built into and seals upon installation. Still a good idea to check for a leak with soapy water and the first regulator set to at least 30PSI. Unit works amazing well. I'm diffusing into the inlet of a Fluval FX6 and injecting for a 65 gallon tank. Running 35psi, roughly 4BPM, it has been holding steady for 8hrs a day. I also run an aerator opposing hours of the CO2 regulator and hit light green on my checker within 1hr of CO2 on. Solid performance. Consistent control. Fine adjustment is great! Note to new folks... Make sure you're setting your BPM after the diffuser has soaked in water for at least 30 minutes and is fully submerged. Otherwise, you'll have false readings (water slows your rate). ... show more

  • Everything you need for co2 in fish tanks
Size: Pro-Se
I’ve been using this for about a month now and i’ve been very impressed with it. Feels very high quality and has everything I need to regulate Co2. The needle valve is very sensitive so it takes some patience to get exactly where you want it to be. After setting it, all pressure and injection rates have stayed consistent. One of the most reasonably priced dual stage regulators with all the features already installed. ... show more

  • Don't buy this
Size: Pro-Se
I've had nothing but issues with this regulator. Unfortunately, I couldn't set it up until the return window had closed. The working pressure valve on these are complete garbage - not a needle valve - and now the gauge itself has failed. Quality control on these is abysmal. After reading online it seems to be a common issue. This is now completely unusable a week after setting up. ... show more

  • Top Quality Aquarium C02 Regulator
Size: Pro-Se
C02 Art's regulator was not my first choice but I purchased this because it is much less expensive than the one that I wanted. It's highly rated by European aquarium hobbyists and I could purchase it here on Amazon, so I rolled the dice. I'm not disappointed and wishing that I had spent the money on my first choice. This regulator is well made, easy to set and monitor and does exactly what I need it to do. I can see why it's so well regarded in Europe. ... show more

  • Very accurate, needs correct washer.
Size: Pro-Se
Maintains accurate bubbles per second.. Prior to purchasing this regulator from Co2 Art I bought 5 different cheap Amazon regulators ranging from $75-125 each. Don’t make the mistake I made, just get this regulator. The bubbles are unbelievably accurate every single day. Just make sure you get high quality washers or it will leak and drain tanks. ... show more

  • CO2 Art PRO-SE Series Aquarium CO2 Dual Stage Regulator with Solenoid CA-PRO-SE-CGA
Size: Pro-Se
I'm happy I went with this regulator instead of a less expensive one. It came neatly packaged and easy to assemble. It's been in use for over a month and I'm very pleased with it.

  • THIS PURCHASE HAS MADE ME MISERABLE!
Size: Pro-Se
Not happy! I saved for months for this reg. At first I thought I had a leak,so I sprayed all the connections with soapy water,turned out I didnt tighten the bolt enough. So I fixed that,no problem. Workimg great,I was ecstatic..5 hours later,working pressure drops significantly. I had to open the knob all the way to keep pressure at 30. Then I realized there was condensation in the gauge. I guess from the soapy water that is recommended to use to look for leaks..idk. I shut it off and have been trying to contact co2art anywhere I could online. I am not a machinist or a mechanic and i am not going to open up this regulator. I want answers. This is not acceptable! ... show more
