My pH tends to stay a bit on the "high" side of normal range.
Typically hovers around 7.8 - possibly a BIT lower, as I'm not the best with reading the pink color gradation on the TF100 kit for some reason.
I have been concerned about it sneaking higher than 7.8, so, I have attempted to lower it now 3 times.
I have added 19oz (measured despite suggestions to NOT do so!!) on 3 separate occasions about 2 weeks apart.
The pH responds by dropping to 7.5, possibly slightly lower, as would be expected.
However, in a couple of days, it is reading 7.8 again
It hasn't, to my knowledge, risen ABOVE 7.8 yet - I just find it strange that there is no "holding" of the pH change - is this typical?
Also - I have a party coming up this weekend and the pool will get it's first true use with a large bather load - many kids, etc.
I'm gonna kick the TC up a couple of ppm prior to swimmer arrival and check immediately once everyone leaves - but, was wondering what expected change in pH I should look for - should I lower the pH to 7.5 the night before or leave it at 7.8?
Thanks in advance for entertaining the newbie questions
