Question co2 diffuser please help?

hi I have got a diy co2 system up and running with an airstone and have recently purchased a glass co2 diffuser with ceramic disk but no co2 will come through I have tried with all my force to blow through it and still nothing comes through so how will diy stand a chance is there something I have to do before it will work like stand it in water for so long etc

would appreciate your help with this as I dont want to upgrade to pressurised and if a human cant produce enough pressure to blow through it what will?

I've had similar issues with DIY and diffusers. Basically you can't build up enough pressure to force the CO2 through the ceramic. I ended up using an air stone with a bell over it to catch the bubbles to allow them to dissolve.

I have some of those glass w/ ceramic diffusers from GLA I use for a DIY application and they work fine.
