There are also pool osmosis services which can remove CH/CYA from the water without having to refill. These usually cost more than a refill but if your water has high CH, it might be worth it.

Re: High Calcium Hardness and Cyanuric Acid
I don't even know how you could measure a CYA of more than 100 unless you diluted your pool water 4:1 with distilled water and STILL got a measure of 100ppm. Nor how you could get it so high.

Re: High Calcium Hardness and Cyanuric Acid
I'm in Gilbert, AZ and have been battling high CYA since I bought this house 2 seasons ago. I just started working on my pool this season and found out my CYA is now around 30, when I started it was over 100. How did you get the CYA reading of 500? If it was from a local pool store, don't put too much value into their test results. Get yourself a Taylor K-2006 kit and test it yourself. As far as high CYA, I just dealt with it and let it lower itself naturally, I had to keep my chlorine levels around 10ppm for the whole season and in the winter I just let the pool filter run but added no chemicals (surprisingly it stays pretty clean, just a little cloudy). I immediately switched to bleach and/or liquid chlorine, this will stop adding CYA too your already high levels as well.

Dubbed, you're responding to a post from last year. The OP hasn't been checking back in, so he's probably not paying any attention to this.
