Can you please tell me what you mean by a non-polymer filter aid when using stain free. I have a sand filter, but do not know what this is.
Thanks!
I believe what you are referring to as a “filter aid” would be a product such as our FerriTabs that will help the sand filter remove the iron from the water.
Products like Natural Chemistry’s Stain Free will remove the iron from the pool surface and put it back into solution. Then a product like FerriTabs will help to allow the iron to be caught by the filter so that backwashing will remove it from the pool entirely.
I hope this helps!
