I bought my house 4 yrs. ago that has an inground pool. I am a novice pool owner and did not have any problems the first two years. Last yr when i opened it, it did not hold chlorine when I first opened it. I had to triple shock it twice and everything was fine. I had the same problem this yr. and the pool still will not hold chlorine. I usually did whatever the pool store told me to do, but I have spent more money this yr. than the past three years combined. The last time I was there they told me I have nitrates, and that's why my pool is not holding chlorine. I found this website and it has really opened my eyes. I was looking around on the website and found some interesting information. I finally bought my own test kit, but am a little nervous using it. I am at my wits end trying to keep chlorine in this pool and am also tired of shelling out a ton of money and nothing is happening. My pool is a little cloudy right now, when I got the water tested here were the results:
This is the first time my Ph was high. I need help. I need a step by step process of what I need to do. Thanks in advance for your help.
