Like many people, I also prepare the CSM+B as a dilute solution and bottle it in one of those brown glass lab bottles (32 oz). I keep it stored at room temp. I also obtained hydrochloric acid (37%) from a chem-lab supply company. I added a teaspoon of hydrochloric acid to the CSM+B dilute mixture.... not knowing if it was enough or too much.
It seemed to keep well for a while, but I went to go use it the other day, I saw the fungal growths. It's been on the shelf for a couple of months, unopened (since I was finishing off a bottle of Flourish).
Exactly how much HCL acid do you think can be added? A few drops, nor a teaspoon's worth, didn't seem to prevent fungal growth.

One should never have to decide between chocolate, cake, or cookies.
