computhan14. Please put your pool info in your sig. It'll help us help you. How did you obtain that CYA level ? If your CYA level is truly 115 you need to get that level down to 30-40 ppm. To do that you will need to do a partial drain and refill. Then you will need to SALM the pool.

With 9800 gallons to lower your CYA level you need to replace about 65- 75% of the water. It may make sense to drain it and start over.
