It depends on a lot of things. Your CYA level, the temperature, the amount of organic stuff in the pool, the swimmer load, etc. The amount of bleach you are using doesn't seem excessive to me especially for a 30K gallon pool. Losing 2-3ppm per day isn't bad.

Do you have a Taylor K2006 test kit? Post some current testing numbers. It may be that your numbers, especially your CYA level, may need tweaking.
