C02 Questions

[Monee]

I am trying to put c02 in my tank. Everything is hooked up but there is no bubbles coming out of the diffuser. I have no idea what’s wrong. Any ideas?

You’ll have to post more info. Is everything open from the tank and there is co2 in the tank right? Maybe stupid questions but sometimes the easiest thing is what it is.

I took off the diffuser and found pressure was fine. I must have a crappy diffuser. It’s a fluval ceramic disc. Can you recommend a good diffuser?

It might not be that it's a bad diffuser but that your working pressure wasn't high enough to push bubbles through it. If that's the case, then finding a diffuser could become more difficult. Do you know your working pressure?

Fluval ceramic disc is a decent diffuser. It needs about 20 psI to produce bubbles. You will have to wait 10-15 minutes for the pressure to build up, especially if you have water in the tube; watch for gas pushing water and slowly filling the airline.
Check for leaks: regulator, bubble counter, check valve.
