I am **considering** draining and refilling. My calcium level is slowly creeping up. It is now at 450 and rising little by little. I am having some scaling around the spa spillover and a few other spots. Getting concerned about SWG cell life.

My fill water is about 190 cal. The water coming off my water softener is about 20 cal. I would like to use the water off the softener as it will require less draining and refilling than using fill water.

Any problems using softened water to fill a pool? I know that our builder didn't want to use it to fill the pool or for the fill line. Perhaps that was a low calcium concern - exactly why I want to use it.

If needed for some reason, yesterdays test results:
