Review on S T International Aquarium Bubble Counter Fish & Aquatic Pets by Sara Bertrand

Bought this check valve combo kit. I already have a bubble counter. I first softened the CO2 hose with hot water and then connected the inlet line. Then I softened the CO2 outlet tube with hot water and attached this line. Both ends are pressed in. Turned on the CO2 and immediately CO2 started leaking out of the check valve and when I turned off the CO2 water entered the check valve and started dripping onto the floor. In other words, it didn't even last. a minute before he failed, he was a failure before he even got here. I haven't tried the bubble counter because I don't need one. I needed a check valve because the inlet nozzle on my Aquatek bubbler with built-in check valve AQUATEK bubbler with built-in check valve (R-131) broke during hose installation. Aquatek simply had to be replaced. Although fragile, but at least it worked.
