How often should water be changed?

Thanks for your response.
My calcium hardness just tested out at 200ppm. This is a freshly filled pool. For Chlorine, I use Tri-Chlor Tablets along with Bleach.

As I stated above, here in Las Vegas, we have some of the hardest water in the country.

A calcium hardness reading of 200ppm is just fine. If you use trichlor, keep an eye on your CYA level as the trichlor adds CYA. Also, it can drop your pH so you need to monitor that as well.
