Floating scum, sputum, and debris shall not be allowed to accumulate in the pool; skimmers, where provided, and water levels shall be maintained and operated to continuously remove such material. The bottom and sides of the pool shall be cleaned as often as necessary to keep in a clean condition. The sides and bottom of pools, decks, and other surfaces shall be kept free of slime and algae to prevent unnecessary slipperiness and danger of accidents or drownings. (Ord. 3440 § 1 (part); June 24, 1975.)
