Trouble With FC Test TF-Pro Kit

I suspect that the ammonia is quite high.

You can choose to continue to SLAM or maybe do a partial drain and refill.

Hard to tell exactly how much total chlorine it will take.

Maybe 10 gallons and maybe 100 gallons.
 
Last year was the first year with this pool and we did not last year. I’m not sure about the prior owners however. Last year we used a local pool company to maintain the chemicals (they only used pucks in our chlorinator). I mentioned before but the last report we got from them before they close the “stabilizer” level listed was at 170 in September. I only ever saw them using test strips to test the water so who knows how accurate their readings were.

I don’t plan on going back to that store or using them for closing/opening again.

The prior owners of the pool maintained the pool themselves.
