Help with algae in above ground pool

[LISAISAACS]

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

If your chlorine reads 3, then you need to add more chlorine til it gets back up to 15.

In order to read higher than 5 with your kit, use one part pool water to one part distilled water, mix well, test from that sample, read results, then multiply by 2. If it's still reading higher than your highest, then use 1:2 and multiply by 3. You'll lose a little accuracy with each dilution, but it's still better than estimating, and maintaining shock level is the only way you're going to get your pool cleared up.

I tested with the 2:1 method and it was a pretty yellow orange like the 5 is on the test kit, so multiplying x 3 would make it 15. I had just added a 3 quart bottle of chlorine after I wrote the last reply. I will test again in the morning to make sure it is still there. Do I need to keep up with the stabilizer or pH right now or just worry about the shock until it is clear, which should possibly take how long? I would like to be able to enjoy the pool this weekend. It is 100 degrees here in lovely SC.

I am having very similar problems. Is it okay to shock the pool to levels this high on the chlorine side, having an above ground pool?

The maximum shock level is in the Best Guess table. If you follow the table it's perfectly safe in A/G pools. Going higher can be risky, though.

What do you mean exaclty by the table?
What level is it okay to swim in when the cholorine is so high?
