I've had my pool for 4 years. Every year I seem to have one problem after another. 2 years of the 4 I had to deal with phosphates. I did not have them until the pool company that I dealt with had be put all kinds of stuff in the water. They tested the water and I had NO phosphates at the time. I researched all the "stuff" online and found that everything I introduced to the pool was pure phosphates. My phosphate readings were off the charts. I never went back to that dealer!
Two weeks ago I had perfectly clear water. With all the high temps here in Ohio over the 4th of July and all the family swimming, I totally forgot to check my Frog Chlorinator. It ran out of tablets. To make matters worse, I forgot to shock after an all day family swim. When I woke up the next morning, the pool was green and a mess. It turned overnight. I shocked with 2-3 lbs of shock every evening for a week until it looked like it was clearing. My chlorine was holding.
My pool never cleared completely. The deep end is blue, and I can only see down about 4 feet. And, I cannot get a chlorine reading, even though my Frog Chlorinator is opened full.
Here are the details about my pool:
Test done on 7-23-12:
Alkalinity - 98
CH - 220
Free Chlorine - 1
Total Chlorine - 1
PH - 7.4
Stablizer - 40
Phosphates - 0
I just tested the water and there is no Chlorine reading, and my Frog is wide open. I called a local pool dealer wher I have been purchasing chemicals, and they told me that the algae is not yet gone and to keep shocking. 2 lbs every evening. How often should I backwash?
I feel helpless and confused.
