I swapped out DE for Perlite looking for a more organic solution after tiring of the mess DE leaves in my yard. Filter wise, this seems fine so fine, but there's little balls everywhere, especially on the sides of my pool. I even pre-mixed the powder with water prior to adding to my skimmer. I imagine these will eventually go away, but it raises serious concerns with the the consistency of the product and ability to filter out the finer particles.
Little white balls everywhere!
