VIV820-20 Sea Skimmer Glass Nano Protein Skimmer

This skimmer is great, it was easy to set up, took only about 5 min, directions aren't very clear but its a simple device.. the skimmer comes packaged inside of a bamboo tube that looks pretty cool, they say to use it as a res for skimate but i wouldn't do that as it would either begin to leak or smell too much, so i just hooked a plastic water bottle to the skimmer as a reservoir, the skimmer takes a day to break in, it comes with an air constrictor device that is ok, but i purchased a separate screw valve to better control how much air goes in to get that perfect skim, i have this mounted on a 20 gal reef that is heavily stocked with coral and 4 fish, it works well and has been giving me dark thick skimate.
