I have already been down that road of treating phosphates. Right after July 4, I had extremely cloudy water and took it to the pool store. They said my phosphate level was off the chart and gave me Sea Klear phosphate remover and five bags of shock and told to "come back with sample in 48 hrs". I did what they said and nothing happened. Took the sample back and they said "oh, you still have a high level of phosphates". They gave me PhosFree this time which did cause all the stuff to go to the bottom and were able to vacuum to waste. The water began to clear somewhat but then started to get a green hue to it. Well, I double shocked with the stuff from the store and it caused the "phosphates" to drop to the bottom of the pool again and we vacuumed to waste again. After that, things just went down hill. We found algae under the steps and brushed it up and then I found this website. I have already added 10 quarts to the water and it is beginning to clear. You can just barely see the bottom and things are settling to the bottom. According to my five way test from Wal-Mart my chlorine level is 3 right now. I am not quite sure how to read it and see if it comes to 15. My stabilizer is now at 30 instead of 40 (from the pool store reading). If anyone could tell me how to read the test to the shock level I would appreciate it. I have learned more on this site since Sunday evening than I have in two years of owning my pool.

Thanks again
