M.S. jus' said;

"If you ph is that high add some dolomite lime to the top of your buckets, this will drop you ph even more,. . ."

That is quite incorrect.
Lime, is alkaline and will raise your PH.
That is exactly the opposite of what you wish to accomplish.

High PH >7 is alkaline.
Low PH<7 is acidic.

Clear?
Excellent, carry on.
