Depends how much you splashout. Only a few ppm are "consumed" per month. Over the season, you might expect the CYA to drop by ~20ppm due to all factors.
The CYA buffers the chlorine. If you follow the recommended FC/CYA levels, your pool will be about a factor of 10 less harsh than if you went to the indoor pool at the YMCA on Magee
Replacing water would be cheaper than the risk of trying the CYA reducer IMO.
