Are you asking about the surface attachment for the skimmer? If so I would leave it on permanently, as far as I know the majority of proteins collect on the surface of the water so it is ideal to skim the water surface, thus the reason why coast to coast overflows are popular as they 'skim' much more of the water surface which results in a much more efficient process of getting these down to the skimmer.any one please, help me here
