Aquarium CO2 Regulator Dual Pressure Gauge with Bubble Counter and Solenoid Valve

This regulator is very nice and has a tool less scuba style valve connector nut and it's very compact.Solenoid runs super cool, not hot at all.Has a nice high quality chrome plated finish.Nothing bad to say about it.

It is on the small size but works well.Easy to install I wish they had a extra 0 ring with the kit , it is a single stage regulator with twin small gauges so be careful with the amount of c02 gas you have in the tank .The small 12v solenoid works good after running for seven hours no heat at it at all .I give this regulator A+

this regulator works well only thing that need to be done is to add water to the bubble counter which takes less than a minute

This is a great little regulator and hasn't shown any problems but I'm having to buy a different one because I didn't know about "end of tank dump" this is when a single-stage regulator quickly empties its contents due to the drop In pressure in the tank, the output pressure increases this can cause excessive amounts of co2 to be dumped into the tank, killing the inhabitants. You can avoid this by checking the regulator tank pressure readout and refilling the tank before it gets too low or buying a dual-stage regulator that keeps the outflow pressure constant and doesn't have an outflow pressure spike when the tank pressure drops.

This is a well-built regulator and fit onto my CO2 tank perfectly. It replaced an FZone unit that was a few years old after it just suddenly stopped sealing properly.One benefit of this unit over others I've used is the placement of the solenoid. It is positioned more off to the side away from the tank. It works perfectly and I think the regulation dial on the bubble tank is able to be fine-tuned a little better than most of these devices I've used.At some point the builders of these units are actually going to install one on a large fish tank and build a power adapter with an appropriately long power cord on it, instead of these anemic 3 or 4 foot cords. Unfortunately this unit doesn't do that, so I've had to continue using an extension cord to reach the length of my tank and cabinet, but this isn't a unique problem to this device.The gauges are a little bit small, but they are readable, and that's all that really matters for them.I have a slight concern with the durability of the power connector to the solenoid. The solenoid control is on a small piece encased in clear plastic attached to the bubble counter, and attaches with a little connector that reminds me of a PCB or motherboard connector. It sits solidly in place but I think can be easily pulled out if something knocks the tank over.If I have to replace the regulator on my other tank any time soon, I will definitely look to this design and brand again. I'm hoping it proves to be more durable than FZone units have proven over the last few years, too.

If you intend to use this regulator with livestock in your tank, think twice. I have a 75 gallon aquarium that is by me most of the day while I work. Twice in one day, the regulator went from reading 2 BPS to flooding my tank. Because I was near the tank, I was able to act fast and everyone survived. Unfortunately the last time happened on a Saturday and by the time I checked on the tank, I lost a large portion of the livestock in the tank. I do not recommend this product due to the sensitivity and inconsistency of the needle valve on it.

First, I'd like to say this regulator is preset. There is no way of changing the pressure coming out except by using the needle valve. That said, it is set at a perfect level suitable for what it's intended for. It's small and super easy to use. It's only a single stage so one must keep an eye on the pressure when it starts to get low but for the price, it's a very good deal, especially for beginners! I've only been using it a few days now but so far so good!

This is a good-looking item and works with precision day after day. I don't even worry about it! It was super easy to set up and does not require an extra O ring because they've built one in!
