Hi Ben:

The pool is 20 years old but I did have the liner replaced last year so I would like to hear about option 1 at least and what it consists of if the new liner helps. The question I have is how did the CYA get this high? Was it using the Trichlor shock and Trichlor tabs? I mean the water in the pool is only 2 years old. What steps should I take to keep this from happening again assumine we get it straightened out?

Thanks
Tom
