An improved skimmer system is disclosed, as well as method of use and manufacture. The skimmer system comprises a base-basket and a moving section, where the moving section has two or more louvres defined therein. During use, the base-basket will likely remain stationary, but the moving section will float-travel along a vertical axis defined by the louvres. The skimmer system enables effective skimming regardless of potential changes in level of the pool water. The louvres within the moving section correspond with a plurality of slots within the base-basket. During installation of the system, a user would first position the base-basket within the bottom of any (existing) circular opening which normally houses a pool skimmer. Then, the user takes the movable section and loads it in on top of the base-basket.
