changing pool water

[aylad]

This will work, albeit slowly--the new water should have 0 CYA in it, so by draining the old and diluting with fresh, the CYA reading will come down. Depending on the CH of your fill water, it should also bring your calcium down, as well.

Out of curiousity, how were you maintaining any chlorine in the pool with no stabilizer? I have a sneaking suspicion that the pool store gave you some wrong info.....

You should really get yourself a proper test kit. The best to get would be the Taylor K-2006. Most importantly, you need to get chlorine into your pool. Unfortunately, if your CYA level is now too high, you'll need a lot, but until you get your good test kit just add a bunch of chlorine to have at least 5 ppm FC or more which will max out your inexpensive test kit. Use The Pool Calculator to calculate dosages and check your water as the chlorine may get used up during the day or fighting algae.

Janet,
I am using stabilized chlorine tablets.

If your CYA is that high, you need to quit using the stabilized tabs and switch to liquid pool store chlorine or bleach, or, the CYA level will continue to rise.

Yeah, I know. Probably even 2 or 3 times before. (More likely 2000 or 3000 times before!!
