Last summer I battled all season with high CYA. It was always between 100-120 so I had to buy a lot of chlorine for maintenance. At the end of last season I drained a good amount of water from my 22000 gallon pool.
This weekend I opened the pool for the first time and added probably about 1/3 of well water back into the pool. I thought this would help lower my CYA but when I measured it today with the forum test kit it was still at 100.
Could this be possible considering how much fresh water I added to the pool? How accurate is the test kit when it comes to CYA and if it is accurate how can I get the CYA levels down?
