Bob, isn't the KH low though? I know baking soda will
raise the KH -and pH will stablize at 8.4 - but I have no
idea what baking soda will do to lower the pH. Seems
like the buffering should also be addressed.

What is the fastest, safest way to lower the pH. My pH is registering at

HCl, (hydrochloric or muriatic acid) is fine. Follow instructions
carefully.
This stuff will kill fish and plants instantly if not diluted properly.
