Deluxe AQUATEK Brass Bubble Counter with Integrated Check Valve for Plant Aquarium

Solid build, no leaks. Works well

Had a massive leakage problem in my current CO2 system. It was a new system, but a faulty design whereas I had to rebuild the Solenoid. The original bubble counters had no seals which I guess contributed to the leak - which was not trivial using a 5lb container in 2 weeks. Contracted the seller and they told me that is how it is. Purchased this bubble counter due to the number of seals in the unit. Put it in about one month ago and have had no leakage and CO2 cylinder is still full. Great part and would recommend this to anyone looking to upgrade their device

All co2 units include a bubble counter. This counter/check valve is higher quality will not leak, get it! Replace what came with your unit.

No leaks first time putting it together. Easy to count bubbles. Be careful when you go to tighten it down its a plastic tube.

The bubble counter is simple, effective, looks great, and easy to use. Just wish they had included this with the regulator from the beginning.

This bubble counter with integrated check valve is of really good quality brass. Simple to install. Works perfectly on my AQUATEK regulator.

Save yourself a headache and by this for your CO2 set-up. I fill it with water only once a month or so. It hardly evaporates. It has a build in check valve so no bother with plastic check valves that fill with water all the time. Solid heavy duty material and leak proof.

Leaked out of the package due to a flaw in the threads being flat on one side that never allowed the unit to seal under pressure.
