Abstract
A process for sanitizing water in swimming pools, spas and hot tubs whereby the level of bacteria in said water is lowered comprising: treating said water with a bactericidal effective amount of a combination of di-isodecyl dimethyl ammonium chloride and copper (II) ions, the concentration of diisodecyl dimethyl ammonium chloride in said water being less than about 60 parts per million parts of water by weight; and treating said water at least intermittently with an oxidant selected from the group consisting of available chlorine and ozone.

A process for sanitizing water in swimming pools, spas, and hot tubs whereby the level of bacteria in said water is lowered comprising:
- treating said water with a bactericidal effective amount of a combination of di-isodecyl dimethyl ammonium chloride and copper (II) ions, the concentration of di-isodecyl dimethyl ammonium chloride in said water being less than about 60 parts per million parts of water by weight;
- and
- treating said water at least intermittently with an oxidant selected from the group consisting of available chlorine and ozone;
- wherein if said oxidant is available chlorine, then about 0.5 to about 30 ppm by weight of said available chlorine is added to said water at least once every thirty days;
- and wherein if said oxidant is ozone, then the amount of ozone added to the water is sufficient to meet the required oxidant demand for said water and is sufficient to result in at least 0.1 mg/liter residual ozone at the ozone discharge into said water.
