I have a problem with my pool being cloudy at the beginning of the season. I have owned the pool for 3 years now, and until recently, I thought it was normal for it to take 3 weeks to a month to clear out the cloudiness. My pool has always been green when I open it, so I shock it several times, and the water goes from green to cloudy blue, then it stays there for weeks. That is where I am now. I went to the pool store, and they told me it was because my phos was >1000, and recommended I add borates to my pool. I know the phosphorus is not the problem, but figured it was about time to give borates a shot, what can it hurt. Here are my numbers pre-borate addition:
32,000 gallon in ground pool
200lb sand filter
1 hp pump
I know the FC is low, that is the lowest it has been since I opened it. I added chlorine afterwards, but haven't checked it since. Why is it taking so long for my pool to clear? Do I need to shock it more?
