    You can get it to work if you add a filter aid. However, it only works consistently with D.E. filters.

    According to the website, it says it will filter down to the same number of microns as D.E. So in theory it should work. If you go ahead this route, open a ticket and let us know your results so we can add it to our recommendations. We'll also back it with our guarantee in case it doesn't work.

    Great question. You add CalTreat directly to the pool water. If there's any scale present it will remove that first.
