I just drained pool water to get my CYA down from 90-100 to 50-60. We were out of town more than usual last summer and I used the pucks since I was not there to add bleach - which I normally use. I am looking for suggestions members may have for keeping chorine levels high enough while away from the house 1-2 weeks at a time without using pucks and adding stabilizer. Thought I would ask before going to options involving others or spiking chlorine level before leaving. Thanks
