I was in Leslie's today and saw a product called Cal Sok.
Inside the bottle is a bag of "stuff" that you put in your skimmer for 24 hours that is supposed to absorb calcium into whatever that "stuff" is.
It's supposed to reduce calcium by 200 in 10-15K pool within 24 hours.
I can't find anything out about what the ingredients are. I did find the manufacturer.
So, I was wondering if anyone here had ever used it or knows any more about it, like what the ingredients really are.
Editing to say I found a document at leslies msds site that says it is an organic polymer family.

So what does that mean to a pool? What is it really doing?
Edited again to say I found several sources that say they use organic polymers in city water treatment. That the organic polymers can be flocculent, coagulent or agglomerent. I'm thinking by the description of the instructions I read while at Leslie's that this particular one must be agglomerent.
Now, I'm thinking that the Calsaway company that brings a truck in to pump and filter your water must be using something like this. Seems to me there was a video of a treatment they poured some stuff in the water that either flocced or coagulated the calcium.
At Wikipedia I found a statement I'm not sure how to take. It says "The drawbacks of polymers are that they are expensive, can blind sand filters and that they often have a very narrow range of effective doses."
What does "can blind sand filters" mean?
Am I close on any of this?
