Should I lower my alkalinity?

21,000 gallons in your pool. assuming 4' depth of the water.

Thanks for all your help. What are the consequences of leaving my alk at 240. As I understand it, it will help my pH stay steady but there must be other issues. I'm new to this pool stuff but this site is a great way to learn and all of you are great help and I appreciate all your input.
Thanks,
Dave

PS my numbers as of today
fc 3.5
cc 0

alk 240

cya 30
ph 7.5
temp 64
water only slightly cloudy but I can easily see the bottom and pattern on the liner of my 30' round AG
