When I've tested for my alkalinity I have a reading of 250. My pool is an above ground, 27' diameter, and vinyl. I saw that the ideal alkaline level is 50 - 90+. I was curious, how high it too high? and if 250 is high, what's the best way to reduce it. My PH is 7.8. I am still on the learning curve of maintaining a pool. This is just my second year.
I appreciate any advice.
