This one seems to contradict the belief that high calcium is helpful.
He's saying that the lower the calcium hardness is, the less work the sequestrant has to do on the calcium, thus making it more effective preventing stains.
I would still have to go along with your advice since my calcium hardness is VERY LOW already, and I've been having such a battle with stains. I am going to continue increasing my CH until it's around 300.
What are your thoughts on this article?
Also, am I reading this right. The sequestrants are usually in liquid form and actually may do some good as far as removing the stains as well as preventing them?
