pH in pond too low - question

[Tony Rivas]

Greetings all,
I have a 2200 gal backyard pond with about 20 2-3 inch comets and koi and
about 1/5 plant cover. This week my pH is at 6.5
How can i get it up to a good range. Can anyone recommend a good amount of
baking soda or lawn lime dust to put in the pond to fix it. Could the pH
have gone down due to a berry tree dropping berries in it all month?

Thanks to all,
joe

decomposing plant life will cause the ph to drop for sure.
I've seen Ingrid/Dr Solo suggest Dolomoitic Limestone -
this will act as a buffer.

I'd suggest cleaning the pond of all debris, and adding some baking soda slowly
to raise the ph

go to wally world or garden center and get organic dolomitic limestone. before using
test it in gallon of water, add 1/2 cup, aerated and test pH after 24 hours should
not go over pH 8.5 or so (pH depends on starting pH).
this pH may be due to dissolved CO2, so get some good aeration going in there too.
what is the pH of water out of the tap?
