One other thing you can try is a "skimmer sock" It goes in the skimmer and collects the very fine particles. You can find them on the internet, or at some pool stores. You can also cut a pair of pantyhose and tie it off and put it over the skimmer basket. As for donating to this site - you used to be able to, but I don't think you can anymore.
