Is your diffuser rated for your tank? I know some needs pressure. If it's new, you need a little bit of time before it diffuses. Did you watch it and it didn't do it or?

1. check for leaks by using soap water on ALL connections between bubble counter and diffuser. Connections close to diffuser can just be kept under water. Watch for bubbles...
if no leaks
2. with diffuser in a bucket full of water turn up bps and give it some time (a couple of hours). The CO2 must go somewhere :)

In addition for checking for leaks, also make sure you're using tubing for co2. Regular airline isn't suited for the pressure of co2 systems and alot times the ends that are connected to a valve, diffuser, etc will become a failure point leading to future leaks. Also if you haven't already try and isolate the problem ie. place the tubing without the diffuser in the tank and if you get bubbles you know the problem lies with the diffuser (could be defective, clogged, etc).

I’m using CO2 tubing. My lines are good. I boiled my diffuser so I’m going to try it again. Thank you
