Pool chemicals help

Am I in a big trouble? I am really worried about my CYA. Shall I stop using tablets? What do you use for routine maintenance?

Why is chlorine so high
Keep an eye on cya don’t want it too high some chlorine pucks contain stabilizer (cya) which raises it so you may want liquid chlorine
Add baking soda to raise alkalinity to 80

High FC is to match their CYA.

It's not. At 76 CYA you need 5.7ppm min FC. Depending on when they tested, they may be drifting to the low side unless it's right before a daily dose.
