great site been reading and have learned allot I have a 28'x52" 17500 gal pool is still cloudy after about two weeks of bleach, vacuming and scrubbing tring to keep my FC up to shock level but my test kit won't test that high for chlorine.
Her are my last reading(7-3) from the pool store
i put in about 1 1/2 gallons of the ultra bleach in the morning and the evening when i get home from work don't really test during the day to see what my FC level is. When i get home i test but can just guess since i can't go over a 5 ppm. Also the ultra bleach that i am using has a green tint to it will this cause the pool to have a green tint? Thanks and i will keep reading
