A water reservoir treatment system for a swimming pool, water tank, spa, or fountain water, which is simple to operate, low in maintenance, and highly reliable. The system preferably comprises, in sequence, a water circulation system, a vortex separator for initial separation of particulates, and an absorption or adsorption filter which may be a conventional pool filter using sand, diatomaceous earth, or paper cartridge as filtering medium.
