Since adding borates our pH was stable at 7.7 now it's down to 7.4 in 1 day.
We have swam in the pool aerated not on purpose but we put the fountain out for the kids to play in but ph has changed from 7.7 to 7.4 this was slow drop over 2 days 7.6 to 7.6 7.7 7.7 7.6 7.6 7.7 7.4 in that order.
What causes ph to drop? I've not seen any factors that can contribute to the drop I've looked.
Test this morning
Borates 50-60 best guess using test strip.
I'm still learning the chemistry of how each thing affects the other.
Is this normal or abnormal
