How is adding hardness going to lower pH?
A very cheap way to lower pH is to add muriatic acid, which is available
cheap at the hardware store. "Dry acid" from the swimming pool place is
good, also, and both are phosphate free.
Consider the source of your high, calcium- and magnesium-free carbonates. It
may be sodium bicarbonate, and the salinity of neutralizing all that hardness
with HCl could be tough on the plants.
