The pH scale is a factor of 10 for each number I believe.
Does this necessarily translate into a difference in time at which the pH can change, or not necessarily because in a pool we also have borates, TA, etc.
Example; my pH rises steadily from 7.5 to 7.8 about each 7-10 days, so I test it about every 7th day +/-.
I have an issue going on (raised-stains-stained-bumps-t21024.html ) where I’m keeping the pH at 7-7.2 for a week or so. Is it true that to keep it in that lower range, I should test it more frequently compared to when I am testing to see it go from 7.5-7.8, because it more quickly can go from 7 to 7.3 than it can from 7.5 to 7.8?
