Sounds like readings from a KH test kit. KH measures
the alkalinity of the pond water. I like to keep the KH
at close to 140. Or a pH of 8.4... I add baking soda to
get the KH reading up.
One cup of Baking Soda to 1,000 gallons of water.
Only add one cup at a time each day until you have
reached the 120 (in your case) mark.
Instructions:
Mix a cup of Baking Soda in a couple of cups of pond water.
Drizzle the mixture around the pond then water the pond to
mix the BS in .... VBG

Hope this helps.

...
my ph test kit says that 7.0 on the reading is neutral.
above is alkaline.......
but, some 'things' (like koizyme) want an alkalinity as a minimum of 80
preferred is 100-120.
where/how do you get those readings???????/
