I am really confused on how to balance my pool. Intex 15x48. Before I discovered this site I have added 8 ounces of the walmart pool shock for the last 4 nights. My fc level is 5 and ph is 7.8 but the water is cloudy. What can I do to start using bleach now and clear up the water. I will never graduate to a larger pool at this rate. I just don't understand the whole water balance thing.
