Description from Amazon: SkimDoctor 1.0 Basket Enhancement Turbo-Charge Your Skimmer Basket! The SkimDoctor is a cleaner, more efficient product designed to be attached to your skimmer basket and turbo-charge your existing pool skimmer. SkimDoctor uses several physics principles to create a vortex in your skimmer and increase surface water velocity. First, the slot in the inner tube of SkimDoctor is partially responsible for speeding up the flow of water, more precisely the flow of surface water, in your skimmer. By forcing water to flow through SkimDoctor's narrow slot, SkimDoctor increases the top surface speed. In more technical terms, when water moves from a wider channel to a more narrow channel, the volume of the water that moves a given distance in a given time period does not change. However, the speed of the water increases. This phenomenon is called the Bernoulli principle and explains why water flows quickly in white water rapids when rocks narrow the width of the water channel.
