The most recent test results do not include CYA, which kinda dictates how high CL ppm needs to be to reach breakpoint. The last I saw, your CYA was 130, which would require Cl to be higher than 12...

The only thing I'm not sure about is maintaining a level that won't bleach your liner (since mine is a gunite pool).

The key is reaching and maintaining high enough CL levels to get on top of the growing algae. By the sound of things, you may not have yet gotten there???
