Abstract
Abstract A swimming pool water purifier encased in the inner wall of a swimming pool, comprises a chamber located behind the wall of the pool and extending out of the pool wall in an opening. A skimmer is placed in this chamber and it has at least its rear wall portion perforated to permit the flow of water through it. Another chamber is located behind the first, and it has a coverable top opening. In the second chamber, a container is placed therein and it holds a solid purifying agent designed to liberate slowly a dissolved purifying agent into the water. The container may have a wall opening of contollable area for maintaining a predetermined concentration of purifying agent in the water.
