I was away for 3 weeks for vacation and left family members to take care of the pool during that time. Everything was going fine it seemed from speaking to them through 2 weeks however there was one day that there were several other relatives over swimming and I think that's where things went wrong. Chemicals were not added after all those people were in and it went South.
Came home to a Mediterranean Sea in the backyard.
Current readings are:
Now, I realize that I may have to drain the pool due to the cya problem which I am dreading because I probably won't fill it back up this late into the summer. Is this the only route to take?
The problem here is that the pH was high for awhile, algae grew, and the cya was too high and there was never enough chlorine in there to keep up.
I need some advice please. Thanks.
