I, too, once had one of the CO2 ceramic diffusers that I bought from GLA. Crap. Mine worked pretty similar to yours - that is, it didn't work. Even after soaking the disk in peroxide and/or excel, i was never able to get nice tiny CO2 bubbles from it. I've found that the quality of the CO2 bubbles is very much dependent upon the ceramic disk. In other words, you get what you pay for. The nicest CO2 diffusers are definitely the ADA brand ones (not the Do!Aqua brand ones, I might point out). I've also tried cheap Chinese ceramic diffusers and they aren't do great either. Although I've only had one so far, I've had good luck with the Aquatek brand CO2 diffuser (though I find it very ugly). Sorry for the bad purchase and good luck getting something else.
