Aquarium CO2 Regulator with Solenoid for Planted Tank CO2 Injection System - Adjustable Output Pressure

This was the 3rd regulator I had purchased from Amazon as the first one I bought burnt out and the second had a stripped female connector upon arrival. This regulator comes with everything you need to securely fasten it to a standard co2 tank and adapters for smaller tanks. It makes absolutely no buzzing sound and is 9f very high quality components. I love the quick diaconnect for the co2 tubing. The one downside is that it does not include a bubble counter so a drop checker for checking co2 levels in your aquarium water will be essential to go along with this setup. After being frustrated with other regulators and their build quality, I finally found the one that is solid and works great. It is a bit more expensive but worth the extra dough in the long run. Excellent product!

Cannot regulate my CO2 bps. The ONLY thing accurate is the color of the connector. I've tried for two days now and have yet to get a consistent bubble count. It slows, or it might speed up. Had it set at first, and 2 minutes later it went to nothing. Adjusted it further and came back in a few minutes to see basically a bubble curtain of CO2. I had to adjust it every time I looked at it. Went and bought a regulator locally and it set the first time, and has not altered. Horrible equipment for that price.

As cool and compact as it looks I'm finding it's not as functional as other regulators. The biggest problem is that it's prone to freeze over. The entire thing turns into a big snowball then the gauge pegs red. It seems to be getting worse as time goes on. I've never had a regulator freeze up like this before, nothing has changed in my environment. 78F/44% . Additionally not having a flow meter/indicator has turned out to be another pain point. Its really hard to tell output if you're using it to regulate gas for a garden. Unfortunately I missed the return window on it so I guess i have a $100 doorstop now.

The regulator is well made, and holds supply pressure accurately, but i am trying to maintain 1 bps and the needle valve is all but useless. the setting is far too sensitive - it is nearly closed and trying to crack it just enough results in too much flow or none. I have been trying to fine tune it by reducing supply pressure, but that is not working too well either. I am going to see if I can replace the needle valve with an in-line one that will allow better adjustment.

Not sure if I'm doing this right.. I've been using fluval co2 kit and just thought upgraded to this with the recommend 20oz paintball cylinder would be better... I've followed the instructions, connected the regulator with the blue adapter onto cylinder. Used a wrench to tighten nut. The more I turned to tighten, the more the co2 was escaping. So I loosened just enough to not hear the co2 hissing thru the regulator. I turned the pressure knob to to 20 psi and adjusted the needle valve - waited - no co2 . Just a half empty paintball cylinder now. I've been looking around for more info but cannot seem to find anything. Need help.Update: hand tighten the regulator to the co2 cylinder instead. Thus far, this product has been doing well.

Using this regulator with a TIPPMAN 24oz paintball tank, CO2 proof tubing, an in-line bubble counter, and a diffuser. The first regulator had an issue so I contacted JARDLI, and the customer service representative was very responsive and helpful. They sent a replacement that arrived in just two days, and the replacement regulator works perfectly! It's been holding steady at 40 PSI and 2 bubbles/second for a week now.I made the following adjustments to the instructions:> applied PTFE tape (aka teflon tape, thread tape, or plumber's tape) like another reviewer suggested to the female sides of the couplings> used wrench to tighten connection between the blue paintball CO2 tank adapter and the regulator CGA320 thread> tightened connection between blue adapter and the actual paintball tank only by hand- no need to over-tighten with wrench!

Built great, does not work with the fluval Cartridges, the head is too small. Luckily I had a 5lb co2 tank and was able to use the including adapter to make it work. Like other users make sure you use Teflon tape on the adapters.Another not adjusting the flow rate is really easy and accurate. I was able to fine adjust it to 1 bubble per min. Which is great for my small tank.

Fail! This thing failed within two months. Literally fell apart. Iti bity pieces. Seller says it has a two year warranty but not answering me and no contact info other than amazon Q&A to contact them. I have six regulators in my fish room. This one is junk and seller unresponsive
