My chlorine level is 7 but my free chlorine is 0. All other levels are within the normal range except for CYA which is low. What can I do to get the free chlorine up?

No. I’m using an actua kit this year
What kit would that be? Because it appears you have some very concerning results, but they are the kind of results that raise an eyebrow and are more likely to be inaccurate than the actual problem they would indicate.
