This is my 1st year of bleach and only my 2nd year owning a pool. Last year I listened to the pool store and spent lots of $$.

I just checked and chlorine was 0. I added 2 gallons which should be 14ppm.
According to my CYA shock would be at 20 ppm. Should I get my chlorine up to 20 and hold it there or is 14 going to be ok. How long do I need to keep my chlorine high?? 2-3 days and try something else or just keep it up until it clears up.

Cloudy has now gone to murky. I am no longer able to see the bottom of the pool.

Please help
