I understand you can MAKE citric acid by feeding starch to black mold (yummy!). However, I'm confused as I've heard many that use citric acid to clean pumps/power heads say that you can save and reuse your citric acid solution over time. I just pulled mine out of storage and found what looks to be a couple different types of mold growing fairly prolifically in the tub. Is this stuff safe to use for powerhead cleaning? Is it even safe? Throw it out and mix up a new batch or maybe add some extra citric acid powder to it? I'm using @Bulk Reef Supply 's product. Thanks for the feedback! Hopefully I can learn something
