One 16-oz. bottle is enough to treat a 400 gallon spa twice!
Cleaning your plumbing is so important... Especially if you have just acquired a used hot tub. Over time, even a well-maintained spa accumulates unseen deposits of oily grime, microorganisms, or other foreign matter inside the plumbing systems and heat exchanger. Buildup of this biofilm inside your pipes reduces water circulation and jet action, and can provide a breeding-ground for bacteria.
About biofilm... Biofilm is a complex association of microorganisms which adhere to a hot tub surfaces, particularly inside the plumbing, where they are difficult to remove. Biofilm may contain bacteria, viruses, mold, parasites as well as dirt and polysaccharides which add adhesion to a surface. It grows in the nicks and crannies within the plumbing systems and jets, forming a slippery film.
Easy to use... Make Spa System Flush a part of your regular maintenance routine. It's easy & economical! When it's time to drain your water, simply add Spa System Flush to your old water (per label directions) and run your pumps & jets on high speed for a few minutes (or overnight at low speed, if convenient). You'll be amazed at how quickly it removes oily films and other buildup from your plumbing system! Then just drain away, harmlessly with your old water!
