FZONE Aquarium CO2 Regulator for Paintball with DC Solenoid and Aluminum Alloy Bubble Counter and Check Valve

Great price for the product. Easy to set up and works well.

Yet again FZONE doing their thing with great fitting products. When buying these products you don’t have to hide them. They look and function great.

Work well easy to set up

The gauges were stuck and never moved. The Co2 was wildly erratic, one minute it was one bubble per second, the next minute it was 100 bubbles per second. I took it out of my system immediately. I really want to like FZone, the price is right but, I’ve had to return every product I’ve bought from them except the planted tank light(it’s awesome). Their customer service is great, very helpful and friendly, unfortunately you will likely have to use it.

This thing is super easy to install. I mean, you screw it onto the tank, you screw the bubble counter in, put some water in it, and connect your air line and you’re done. Just connect the plug to a timer to turn it on an hour before your lights come on and turn off an hour before your lights go out. The needle valve works better than I expected. I have this on a small tank right now for testing, and I was able to get down to 1 bubble every two seconds without much trouble. Yes, it’s a bit sensitive in that range, but nothing so bad that it’s a real issue. I don’t trust the solenoid however. It’s not that it’s not working fine so far, because it is. But it’s only been a couple of days. I don’t trust the longevity of it, and I don’t know if replacements are available. It seems the solenoid is where the real costs are cut here, allowing this thing to be sold for $70ish. The gauges seem to be reading fairly accurately so I’m happy with that too. No leaks either. I just hope this assembly can run for a year without failing.

Really nice and cheap for the price. I got a tippman paintball CO2 tank, which was about 40$, then refills coste about 5$ from Scheels. So pretty cheap in the long run. My only problem is that its really really difficult to fine tune the smaller CO2, the knob can turn a lot, but any greater than 1/4th the turn would be too much CO2 for most tanks. It would be better to have it turn more for less CO2, making fine tuning easier and also so a small turn doesn't end up giving too much CO2.Im using it on a 20 gallon long with aim for 2bps

The solenoid doesn’t work. I can turn in all the way down to turn it off, but even with it unplugged, it keeps going.

I have been using this Fzone Co2 regulator for several months and it's worked perfectly to regulate the Co2 in my 6 gallon aquarium

El regulador se abre constantemente dejando el tanque de co2 vacio en pocos dias. Puse cinta teflón y aun asi se comenzo a girar a las pocas horas

Nice solid little unit. Everything works as it should. The stock needle valve seems to work better than most others.

Cheaper to use a standard regulator and bottle that lasts 13 months over compact set up that lasts 3-4 months. Never was able to get a paintball canister shipped through amazon and CT wanted 100 for one. all the supporting items for the set up were lost during shipping, glass diffuser also broke during shipping. charged a 13.99 return fee on this item. Definition of a head ache. The product itself seemed excellent and I will order an Fzone standard regulator for a 2.5LBS bottle or a 5 pounder.
