Hi...new to the site and this is my first post. I just tested this morning, but didn't write everything down to post. But I do
remember the chlorine level was around 3.0ppm. TA was around 130. But what I don't get is that every few days the ph level
changes. Today it was 7.8, so I had to add a bit of acid. Two hours later everything tested normal. But I just had to add
about a pint of acid two days ago. Is this normal?
