I am suprised how expensive freashwater skimmers are. Intrested in doing a DIY.

looking at it I don't really understand how it works either. I'm in general sorta lost on how the water flows through most skimmers. I get the whole idea of bubbles pull proteins and oils and waste out of the water but the rest is a total loss on me.
