Re: Problem cleaning glass diffusor I would soak it till the smell went away. But next time instead of using bleach to clean it, pull the diffuser above the water line when doing weekly cleaning, and put some H2O2 in it. Leave it like that till you refill the tank, and then push it back under. The algae should die and the disk be clean in about 3-4 days. H2O2 breaks down quickly into water and oxygen, making it harmless. |
