What kind of chemicals do you use to lower pH in your ponds?
Yes, yes, I know, you buy stuff in local pond store.

Actually, the consensus here is to discourage chemical abuse of ponds.

While I am sure you will get recommendations for simple household
chemicals, most feel that in the long run you are better off with a
stable environment. Does that make sense?
If your source water is too alkaline, you can use white vinegar (a
machine distilled product) or muriatic acid (nasty powerful stuff) to
adjust in small increments. One hopes you remember your basic
chemistry classes and remember to add the acid to water then add the
diluted mixture to the pond and allow it to mix well then observe pH
changes. Protective goggles and gloves are required if you use the
strong acid.
Good luck.
