Do you have foam in your hot tub water? Well, it could be a sign that there's bacteria in your pipes. Contaminants like sweat, body oils, and bacteria build up over time inside your hot tub lines and it can cause nasty foamy water. Unfortunately, over time those contaminants become completely resistant to your normal sanitizer like chlorine or bromine. And the only way to clear up the foamy water and remove those contaminants is to flush your lines with a hot tub plumbing cleaner.

So plan to flush your pipes and drain your hot tub every 3 to 4 months. And don't forget to get our free hot tubar cheat sheet at Swim.com Spa sheet.
