Bleaching of CO2 Diffuser

[cbong]

I have a CO2 diffuser that is clogged due to algae growth. Have heard that bleaching can help to clear the blockage. May I know how concentrated should the bleach be?? Would it damage the ceramic surface? Thanks

I just pour undiluted bleach to it.

bleach won't damage the ceramic surface.
you can sprinkle a little gravel on the diffuser to reduce the amount of light, thus algae.
