Experimenting with Calcium Reducer

Previously i had posted my struggles with high CH. I drained the pool 40% when CH went to 450 in March and now back at 440! Fill water at 130 ppm.

Yesterday I added the Lo-Chlor Calcium Reducer. This should bind and solidify the CH so it is filtered out. I had not seen any other posts trying this, so I will report back the results. Should know in 1-2 weeks.

Lo-Chlor is a sequestrant. It mostly helps prevent calcium scaling even when CH levels are high. There is a small chance it will cause a little calcium to be filtered out, but that isn't likely.

Any theories as to where the CH is coming from?
That's an excellent point. CH should never build that quickly unless you are using Cal-Hypo as the chlorine source.

Eliminate the excessive source and the problem will go away.
