Aquarium CO2 Regulator with Solenoid, Dual Gauges & Bubble Counter for Planted Tank CO2 Injection System - Adjustable Output Pressure (Complete Set: PRO-E1)

The regulator is of high quality, but there was only one problem - the thread did not fit the gas cylinder, I had to replace the nut with a nut from the cylinder manufacturer, the regulator setup is very simple, it holds the pressure perfectly, the electromagnet works very well and does not heat up.Thank you for your service.

Regulator works well so far. Came missing an O-ring which was a PIA. But got it set and working good. It's a little too sensitive in the needle valve, makes it tough to tune in just right, but otherwise it's decent for the money.

Funciona excelente sobre todo por la perilla negra frontal ya que ayuda mucho en la estabilidad del flujo de salida del Co2.El selector lateral de salida de burbujas es muy preciso.

Works perfectly

I wasn't planning on taking the plunge (see what I did there?) into CO2 enrichment for my aquarium, but I couldn't resist the opportunity to try out this cool regulator from JARDLI.I actually went out and bought a couple of 20lb tanks (make sure you ask for "beverage grade" CO2) and ordered a nice stainless steel emitter here on Amazon just to review this product (that's I told my wife, anyway).First impressions...This thing looks really slick. It makes me wish I had a nicer looking tank. I also really like the solenoid controlled valve that allows you to attach it to a timer so that you only run CO2 when the lights are on.Not so great...The bubbler is not completely watertight. The regulator and bubbler knobs are incredibly sensitive and hard to dial in to the exact setting you want. Even if you get your perfect flow rate dialed in, the on/off cycle will wreck it. The next day, you'll have to play around with it again to dial it back in, which sort of defeats the convenience of having it turn on and off automatically each night. I suppose everything is fine if the flow is too slow (which is what happened to me), but what if you wake up and the flow is way more than it should be? It could kill all of your fish. I understand that external factors like temperature, barometric pressure, and the amount of gas left in the tank will all affect the flow rate, but there has to be a better solution than readjusting it every morning.All in all, though, it gets the job done with no leaks (I checked every joint with soapy water). I'm mostly happy with this item, but the constant daily readjusting is a real chore. if I wasn't receiving it for free, I would probably shop around and try to find one that has more reliable and permanent settings.

Quality build regulator for CO2 aquarium installation in planted tank configurations. Have used other Jardli equipment which has worked as designed without failure.

Después de varios meses de uso es Perfecto para usar co2 en el acuario de forma sencilla, solo tuve que añadirle un conversos adicional para adaptarlo a una botella de paintball la válvula selenoide funciona Perfecto nunca eh tenido problemas solo me falta comprarle un temporizador y listo funciona Perfecto
