Occasionally vinegar is also used where it's acidity isn't an issue.

And molasses is an organic carbon used in the aquarium industry as a treatment? The reason I'm asking is I'm wondering about using molasses in my koi pond. Similar to using barley straw or its extract to compete with string algae?

I've never heard of it being used in aquaria, although I have heard of sugar being used. I'm not certain of the dosages for anything other than ethanol, which are extremely low.
