New DE Filter. FC is at 6ppm and CYA is at 50-60ppm. Been losing approx 1ppm of FC daily. Noticed more debris collecting at bottom of pool again. Not sure whats going on. Is it just dirt/pollen/debris from trees or is it algae growing? Its been clean for a few days now and I am starting to see more stuff collect at bottom since yesterday. Been battling this for 4 years and always thought it was my old cartridge filter but now with a new DE filter, it must be algae? What do I do? When I brush it up it puffs into a slightly yellowish cloud. My water is crystal clear and I have no visible algae (green etc) on sides or bottom of pool. Just these little clumps of debris in the crevices at bottom.
