Last year we had some repair done to our liner at the beginning of the season (our second to own the pool). So the pool had to be drained and then refilled half way. It was no surprise to me when our pool store (a local mom and pop) tested our water and told us that we needed more stabilizer. We added it.
I normally do all of our testing, and stupidly, I never tested the stabilizer after that. We had problems with chlorine all summer. Toward the end I was fed up and took a sample into the company. They read that we had no stabilizer! So we added it and go it back up to proper level.
The season (our third) we are getting a late start, we just started opening the pool. Took a sample in and guess what? No stabilizer.
I am at a loss and so is the company.
We havent added any more water to the pool than normal evaporation or loss from backwash. The first season we didn't have this problem. I would think that maybe the level would drop, but not completely! Especially when we use tabs with stabilizer!
I dont want to fight my pool this season. Any ideas why we would be losing all of our stabilizer?
