Low Cya and it won't go up

Have you tried:
1) getting fresh CYA reagent
2) having your water tested somewhere to see what they get for CYA?

Even with high ammonia levels in the water new CYA should register on testing.

Also, Is this an inground or above ground pool?
How often do you need to top it off with new water?
Do you have an autofill on the pool?

I closed it right before it went down to freezing and opened it as soon as we had no more freezing. The bad thing was it would go to 80 degrees one day and drop to 0 for a few days. When I opened my pool it looked like a swamp. After adding chlorine I had frogs popping out like corks. I do what you said and hope for the best.

I did buy another container of fresh CYA.

I did not have the water tested elsewhere, I do now have three test kits that I used and tested other pools using them and they all worked fine so I ruled ot test issues.

Above ground pool 24'X52"

I have not added much water this year. It was just about full at the start and I haven't needed to add much this year. The weather has been good so we haven't had much evaporation so far, much less then other years.

No auto fill.
