You are right, my pH does change rapidly and I am still trying to figure
this out. If you notice...the pH was pretty steady at first. The changes
started once the nitrite started to increase.
=============================
To help buffer and keep PH more steady I use cheap oyster shells from the
freed store meant for chickens. I also have limestone rocks in some of the
pools. Rinse the dust off the shells, bag them in a mesh bag and put them
in the filter or near an outflow from your pump.
