What does a protein skimmer do? Protein skimmers actively remove waste products from fish, plants, and invertebrates (along with any dead organisms or uneaten food) before it has a chance to break down and compromise water quality.
Skimmers are often used in conjunction with booms. A skimmer is a device that collects and removes oil from the surface of the water. Skimmers can be towed, self-propelled, moored in river currents, or even used from shore. Many types of skimmers are available for use, depending on the kind of oil spilled and the weather conditions. Weir skimmers work like a dam. Oil flows over a wall and collects on the other side. Oleophilic (oil attracting) skimmers attract oil with belts, disks, or mop chains so you can just squeeze or scrape the oil out of them. Suction skimmers work like your household vacuum cleaner.
