Low chlorine reading

I forgot to add those.

Calcium hardness 250
CA 30


I am getting a better tester kit because I can see that I can trust my numbers more than the pool stores.

By the way, store #2 called back and suggested hitting my pool with 19 gallons of chlorine to super chlorinate but I am going to go with 6 gallons as suggested here and retest in the morning

Yep.

Lower the pH
Add chlorine each evening
Check chlorine each AM
Do not use mega-doses of chlorine
