No! Unlike Chlorine or Bromine the water in tubs treated with our natural products is not caustic or corrosive; it is good for your skin, good for your hot tub, and good for the plants in your garden where you drain your spa.
Our products do not plug up filters like Bromine or Biguanide, do not oxidize the plastic in you tub like traditional chemicals, (making it chalky and brittle), or attack metals.
Your tub will work better and last longer with these products.
