Water is too hard

[duraleigh]

How do I get the CH down? Partial draining?

.........Yes.

That said, I'm not sure you need to. CH levels seem to vary widely in pools and, if your pH and Alk are maintained correctly, don't seem to cause too much problem.

If the upward climb in CH is a trend, I would try to identify the source and eliminate it. Assuming it's not your fill water, partial draining and/or splashout should trend it downwards. I don't think the CH level is at a danger point of any kind but, you're right, it's at the upper limits of what most folks recommend.

Thanks Dave.. I'll keep an eye on the CH and the associated trend.
