I have a 14k gallon inground, covered pool. The water is crystal clear, and there is no visible algae. However, the pool will not hold chlorine, and I am losing CYA over time (without water changes).
Based on this article (poolsolutions.com...), I have been under the belief that some kind of bacteria is consuming my CYA. So, for the past couple weeks, I have been shocking the pool to 10ppm every night. When I tested this morning, it was at 5.5ppm. This demonstrates some progress, as almost all of the FC was being depleted overnight when I tested last week.
Is this being caused by bacteria (and so I should continue shocking pool every night)?
I'm wondering whether it could be something else. Like, the water maintains at 88-90 degrees. Could this temperature be somehow leading to the FC and CYA loss (as is suggested here: blog.orendatech.com...)? Obviously I'd prefer not to be wasting money on gallons and gallons of bleach, if the CYA and FC loss is inevitable at these temperatures.
PH is 7.6
CYA is in the 20s (was ~45, but I'm rapidly losing it over time)
Thanks!
