I am new pool owner. Have opened it and got rid of The green. My water is now milky and it doesn't seem to be getting any more clear. I have shocked and added PH decrease and keeping a chlorine tablet in the skinner. The last test I done on water the ph is now showing to low on the test strip. Everytime I go to the pool store it's here's your chemicals add these and come back!!! Any help or suggestions!!!! I'd like to swim in clear water.
