The carbonate is acting as a buffer... you want to add acid to the water
to decrease the pH, not another buffer.

Got a friend with an established pond or aquarium?  Borrowing a few
buckets of water from them is often the fastest way to get a new pond or
aquarium to "settle in", and then you can adjust from there.

Carbonates can buffer soils in the same way as water.
