Have been trying to get chlorine reading on my pool for over a week with no success. I started by add 4 lbs of granule shock and nothing. Then I was told to add liquid chlorine so I added 3 gallons and nothing. I took water in to get tested and they said alkalinity was high and ph low. So I added a gallon of muriatic acid waited a day, then added ph+ When alkalinity and ph were acceptable, I added 5 gallons of liquid chlorine and still nothing. This AM, I took sample to a different pool store. They said everything but chlorine was fine and suggested I had chlorine with stabilizer. I added 5 lbs of super soluble. It's been 8 hours and I still have no chlorine reading. This AM results were:

Total Chlorine 1.2
free Chlorine .5
ph 7.5
alkalinity 147
total hardness 140
CYA 30

On a good note, it started out cloudy and is now pretty much clear. Please help!
