Abstract
A swimming pool is treated by a mixture of sodium carbonate and cyanuric acid or sodium carbonate alone added in the form of a compacted tablet. The tablet is placed in a leaf skimmer or in a bypass cartridge connected to a swimming pool recirculation pump parallel to a pool filter. The tablet is formed by depositing a mixture of sodium carbonate and water in a vessel and by applying pressure to the mixture.
