Any suggestions on my latest test results? I've been trying to get my CYA levels up, yesterday they were 20.
Another thing I've notices is what appears from the surface to be areas of sand on the floor of the pool. As I approach them and attempt to pick them up with the vacuum they disappear. I just did a full drain and refill, any idea what this is ? Water is crystal clear. Suggestions?
TC - 3 (looked like 3 to me on the test kit)
FC - 3
CC - .5
CH - 100 (trying to raise this, I have a gunite pool)
TA - 160
PH - 7.5 (ph was 8.0, added small amount of muriatic acid)
CYA - about 15 (was 20 -- > 30 --> now 15)
