Isn’t it normal for spa or hot tub water to have foamy bubbles?
Foam in a spa is never a good sign. The foaming water is a reaction derived from water that is not balanced mixing with bathers wastes. A bather in a spa adds 3 pints of sweat to 100 gallons of water in an hour. A swimmer adds only 1 pint of sweat to a 20,000 to 30,000 gallon in a pool! Properly treating and balancing the water is a must. Not only will it eliminate the things that can cause your spa to foam, including body oils and soap residue, but it will protect you, your family and your investment.
