Build a surface skimmer:    • HOW TO: DIY Aquarium Skimmer  

In today's video, I'm going to show you how to build a protein skimmer for a saltwater aquarium.
A protein skimmer removes waste products or basically any decaying organic matter in a fish tank before it has the opportunity to break down and lower water quality.
It does this by passing water through a skimmer, dissolved organic compounds in the water attach to the bubbles the skimmer produces. As the air bubbles rise, so do the organics now attached to the bubbles. The organics are then collected in a cup at the top of the skimmer and removed from the system.
