My Dolphin came with 2 sets of filters, which filter should I use?
The Dolphin is shipped with the Fine (screen mesh) filters installed.
The Fine filters collect large debris (such as leaves, grass, twigs).
Depending of the models, inside the box are the Ultra-Fine filters (pleated, corrugated) which collect small debris (such as dirt, sand, algae).
