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

The media could not be loaded. i use this co2 regulator on 4 different tanks now. I have never had any issues. i have never seen an “end of tank dump” with these regulators either. The solenoid works great and its easy to have consistent bps

It arrived quickly and was packaged nicely so it arrived in mint condition. I've had low tech plants for a few months now, and recently got into co2 setups and this regular comes with everything you need. I attached it to a small paintball tank I had connected all the hoses and it was ready to go. No leaks, its not made of plastic which increases its value, it fit snug, did I say no leaks. If I had known setup would be this easy I would've added co2 to my tank sooner. Its precise and the readings are consistent. The nozzle is high quality and was very easy to make adjustments. I will purchase another one once I convert my next tank to co2.

TL/DR for newbies like myself: Let me just tell you not to freak out if you screw the regulator onto your full Co2 tank and it doesn't work. Plug the solenoid in first and THEN try to use the needle valve. (thank you customer service) :)Also get some backup paintball O-rings AND gel silicone lubricant for the O-ring. If that thing breaks, your tank will leak until you unscrew the regulator. Also speaking from personal experience.Now onto my paintball/Co2 noob experience:This was my first time having REAL Co2 for my fishtank. Before I was using the Fluval setup that uses the 16g throw away cartridges. So even though I did reading online and had friends helping me, it was still just reading...no hands on experience. I ran across this regulator and wanted it because it didn't need any adapters and I could just get a paintball tank.When I came home with my newly filled 20oz Tippmann paintball tank and screwed on the regulator, it chewed right through the O-ring that came with the tank...and dumped half of the Co2. That was a "fun" evacuation from the room for 10 minutes.So I got some O-rings from the local army surplus/paintball shop, regulator chewed right through those as well. THEN I ended up ordering some red polyurethane paintball O-rings off here...and figured out that you need a silicone lubricant for them...woops!Because I'm new to this, when I screwed on the regulator and turned up the needle valve, nothing was happening. Great...I got a broken one.So I contacted customer service and long story short, you need to plug the solenoid into the wall before it'll work...oopsie. Finally after over a week of this mess (all caused by ignorant me), I got this thing setup and working after same hour(it was more like minutes after messaging them)help from customer service.This regulator has also saved SOOO much money as I no longer have to buy 16g threaded Co2 cartridges in bulk that only last a few days each. I have the solenoid(which has been silent) plugged into a timer and it's been working great. The needle valve is very precise as well.So all in all it's been a great thing to have for my aquariums...don't be afraid to try this one, customer service will gladly help you through any trouble or silliness you might encounter.

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.

I’ve had this for three days, two of which were incredibly frustrating. I set everything up, it seemed to be running well, it was coming out of the diffuser very little, but I figure since it was a new diffuser it just needed some time to ‘break in’. Not the case. The bubble counter was leaking through the threads. It took me a while to figure this out, as it was very quietly leaking, but it was leaking fast enough that the diffuser completely stopped diffusing. I had to go to the hardware store for an O-ring for the bubble counter, and now everything works great, so far. Regulator doesn’t seem to run too hot. There is an LED indicator when it’s on, which I like as well. I willUpdate if anything changes but, outside of the missing O-ring, I’m satisfied.

The regulator feels very solid in terms of build quality. There were no instructions included. However installation is as simple as screwing on the regulator to paint ball tank , filling the bubble counter with water and attaching it to the regulator / CO2 diffuser. Didn't have to use teflon tape at joints since it uses the paint ball tank' O ring for sealing and there is another O ring for bubble counter. Tested for leaks at joint using soapy water + a brush and there were none. The needle valve is easy to adjust and maintains the bubble count once adjusted.Attached to a timer, the solenoid works like its supposed to. Hopefully it lasts long. The solenoid seems to be integrated and not sure if it can be swapped out in case of a failure.

I wanted to like this product but it’s cheap. It worked great on the first co2 bottle as I set the tank up but on the changeout to a new bottle it leaked. Not worth the cost. Would rather spend the $ to get a better product
