I changed out 80% of my water because of high CH and CYA. Now, there's no CYA in my pool. So, I went to the pool store to pick up some "stabilizer". I picked up a 1.5 pounder because I wanted to see how my pool was going to react to just that much. I think I will probably end up needing more, but then I remembered that the original owner of the house had some chlorine tablets leftover for me. Lo and behold, they're tri-chlor tablets which after doing some research I understand that it raises CYA. SOOOOOOOooooooooooooooooooo.... Would it be ok to use the 25 tablets that are leftover to slowly raise my CYA the rest of the way, or should I do it immediately with more stabilizer? Paying $11 for 1.5lbs of the dry stuff isn't on my sounds like much fun list at the moment.
