Automatic chlorination setting

Use a floating dispenser.

What is your current CYA? Your signature shows you use pool store testing. Not TFPC method.
 
OK -- 5 8 oz tablets will raise your CYA by about 10 ppm. So you will end up at 60 ppm.

It will be impossible to add enough chlorine each day with tablets. But you may get by for a week. Fill the floating dispenser.
