First off pool looks clear and blue. No real problems. But I've noticed some trends with the numbers I want to know if are normal or may indicate anything wrong.
My numbers taken this afternoon:
FC - 8
CYA - 55
PH - 7.6
TA - 100
CH - 400
Temp - 80 degrees
The pool is almost 4 months old with a SWG and Pebbletec finish.
First off when the pool started my CH was around 270. So it has risen 130 points in nearly 4 months. I understand new plaster raises CH. Would a rise by 130 be normal?
Second, my CYA tends to disappear at a rate of about 5-10ppm per month or so and we havent really much splash out. Is that a normal reduction? It was at 70ppm at the end of November.
Third, my CC has been hovering around 1 for about a month or two. But not having much loss of FC. My SWG is on the lowest setting. I even had to turn it off for a day last week because my FC was getting too high. When I add water to the pool, there is also a chlorine smell that doesnt exist any other time.
Thanks for any advice.
