While backwashing the filter we accidentally knocked the bucket of DE into the pool instead of the skimmer. There is now dust on the bottom of the pool - should I just keep brushing this into the drain? Will it ever go away and/or how long will it take? Is it safe to swim? Also wondering if I should backwash the filter again and add more DE into the skimmer? Help!!! I really appreciate anyone who can offer some advice! Thank you so much!!!
