If anybody can help, please go to the linked thread. This poster has been fighting an algae problem and recently posted that he is having backwashing issues. So, to keep all his "history" together, instead of starting a new thread, I just want to refer our equipment gurus to link over to that forum. (I know some of you don't read the chemistry threads and thought you might not see it as a result.)
