Waterline Accumulation – Bromine and Chlorine

A buildup of oils and other body waste, combined with higher water temperatures can cause waterline buildup in spas. To prevent buildup, shock the spa reguarly, especially after heavy use, and maintain proper water balance, and use a spa surface cleaner to periodically wipe the hot tub surface clean. Use only a soft bristle brush or sponge to avoid scratching the surface. To remove heavy stains, allow the cleaning solution to soak on the stain for 5 – 10 minutes before scrubbing and rinsing.

Note: This information is intended for a residential spa with average use. It is not designed for public, commercial, or semi-public spas. If your hot tub is used more than three times per week, you should check and make chemical additions more often than suggested.
