3 days ago, I added DE to the sand filter, per the instructions and the pressure increased 20% within 24 hours then I backwashed and rinsed.
Yesterday, I added more DE and the pressure only increased about 10% but the skimmers were not skimming well. Lots of debris on the top of the pool. So I did another backwash and rinse and the skimmers were back to normal, pulling debris.
Does this mean I need to keep adding DE and backwashing as soon as the skimmers aren't pulling in debris, regardless if the pressure gauge doesn't increase by 20%?
