Ph Question!

    is it normal that when adding ph down a small ammount will cause a large fluctuation, & when adding ph up a large ammount will cause just a small fluctuation in ph?

    depends on the strength of the PH up and PH down. so yeah it could be normal if your using a strong PH down and a weak PH up ;)

    Im using potassium hydrodroxide for up & phosphoric acid for down, does this make sense? pretty sure theyre both 80%
