We've had the pool now for 2 years and following the TFP techniques is working perfectly.
However I have one questions. Being in Canada, we close the pool for about 6 months of the year. When I open the pool, the CYA has dropped to 0. I would expect it to drop some, as we get some overflow from snow melt and spring rain, but it doesn't make sense to me that it goes to 0. When I close it in the fall it would about 70.
Last year, I replaced the chemicals we use to check the CYA, but the new chemicals gave the same reading.
This year, we are back to 0 after the winter again. Is this normal?
