You can not test the pH when the FC > 10ppm ... stop trying to adjust it.
Low CH does not matter in vinyl pool.

Alright friends:
Pool Temp 80 degrees
FC: 7
CC: 0
Alkalinity: 180
PH 7.5
Should I do anything about the alkalinity?
There is no reason to actively worry about the TA. But, if you want to: Lower Total Alkalinity
Just make sure you FC stays above the minimum for your CYA.
I'd keep the pucks...you might need them someday to raise CYA.
I have a tub of pucks and shock, though I'll likely never use them.
Looks good. Your TA is a bit high, but it won't cause you any big problems. Your PH will rise quicker with the high TA, but you control that with acid to bring the PH back down. Acid will lower both PH and TA, so over time your TA will come down as well. I added too much baking soda to my pool once and sent my TA up to 140 but it didn't cause any issues.
It is normal to have to add 2-4ppm of FC everyday.
That is a bit on the high side though ... what is your CYA? Might want to raise it.
Oh, well then you are under 3ppm a day, so that is pretty good. Although you are going to want to raise the CYA up a bit if it keeps dropping from the rain.Sorry, I meant 15000 gallon pool.
