I have 2 questions regarding PH readings:
1. Do they make a test kit, or strips, that can read higher than 8?
2. Is it better to put acid in when the water is circulating or still?
Reason for question #1 is I have a salt water pool, and I have to adjust my ph all the time. My Taylor kit only goes to 8, and I thought when it was indicating 8 I added about 1/4 of a gallon of acid and the next day it was still reading 8. So I added more until I got it down to 7.6.
Reason for question #2 is when I bought acid, the person behind the counter said would work better adding it in the deep end without the water circulating. I asked why, and he said you use less acid and it won't impact your Alkalinity.
