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

It’s good product, CO2 bubbles are very stable, it has an additional valve, so CO2 bubbles counter easy to remove, diffuser disk is replaceable when old or bad . It’s compact than other brand but work much better . I recommend it with 5 stars

This regulator works very well and don't believe the other comments where they talk about CO2 dump must the cylinder is low. This regulator will not dump on a low pressure.

I’ve been using this regulator for quite a while and it’s been completely problem free

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.

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+

The unit does not have a way to control the pressure of the second stage- making it essentially useless. The picture they provide makes it appear that the front "knob" can be turned to adjust that second stage pressure. Very misleading. My diffuser requires 60psi and this thing would only hit 30. Spend more and get something you can adjust. I would have returned this had the box not been thrown away.

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.

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!
