Question about Buffering Capacity in pond!

Plaster of paris from lowes also works well. Fill the bottom of a laundry
basket, let it harden and dry, put it in the filter or out of the way.

OK, so I got a pond kit to test my bond.
I read it as the ph level was too high and the total buffering
capacity was too low. According to the instructions I have to add
Sodium Bicarbonate (baking soda) to bring it up.

My question is, is the standard baking soda in the grocery store ok to
use as long as I just get pure baking soda? If so how much should I
add?
My pond is about 2000 gallons.

Thanks for the info.

plaster of paris is not a good idea. Rod Farley explained why. but the result is pH
levels that swing up and down and dead fish. use organic dolomitic limestone instead
for hardness. but they have high pH so they need an acid like HCl or muriatic acid
to bring the pH down. Ingrid

This weekend I'm happy to report pH is holding at 7.8, KH 107ppm. String
