If you watch a skimmer for a number of days you will notice that the amount of debris collected drops off over time. This is because the rising foam deposits some of the fat and protein that has collected on the riser side. These deposits make it more difficult for the foam to rise and thus the amount of residue in the glass decreases.

The Deltec scrub head is a manual scrub head that includes the silicone scoop blade cleaning of the auto scrub heads and is powered by simply turning the skimmer cap by hand.

By turning the lid 1-2 times the neck of the skimmer will be cleaned and the skimming efficiency will be optimized . The head must be turned at least once a day to prevent building deposits in the neck.
