View Full Version : Surface skimming

Can anyone explaine surface skimming? I'm wondering with the water movement in reef tanks does it matter where we collect the water from.

a film seems to collect on the surface of the water no matter what so when you surface skim you clean that right up and presumably get it to the skimmer
