Aquarium CO2 Regulator with Bubble Counter Solenoid Check Valve Adjustable for Standard US Planted Tank CO2

Muy buena calidad 👌

I bought this to replace a Fzone brand regulator that started leaking from the plastic attachment after 2 years of use. This one is all metal and seems like a solid construction. I am able to easily adjust the flow unlike my fzone which I had to constantly tweak to get it where I wanted it. Going from Fzone to this was un upgrade and it costs less.

This unit is super loud and annoying, its almost unusable. If you planned on having this anywhere you have people near by then maybe it might be a good option to get a different regulator.

Bought this as a replacement for a failing 20 year old setup. I'm very pleased with it. The unit adjusts easily and holds the setting very well. Highly recommended!

every time the solenoid turns off and then back on, the CO2 flow changes.

The tank pictured doesn't have a collar, but every CO2 tank I've seen has a big collar that can't be removed without special tools. When this regulator is installed with the bubble chamber in a vertical position, there isn't enough clearance between the solenoid and the collar to connect the tank. In order to achieve a seal between the tank and the regulator, I had to rotate the regulator, and now the bubble chamber is tilted about 45°. It appears to work, but it still seems stupid to me.

I’m surprised with the effectiveness of the regulator considering its price, I put this on a budget Co2 paintball tank and it works like a charm even tho the bubble counter is horizontal. Highly recommend for an aquarist seeking to save money on a tank

First time looking for something new to try and ran accross this. Had it for a week and it’s very easy to use.
