eco3spa Step 3 - Multi-Function Water Sanitiser Tablets rapidly dissolve in water to release a form of Oxygen called Active Oxygen. Active Oxygen is a powerful bactericide and oxidiser. The Active Oxygen kills any bacteria in the water and oxidises (neutralises) any organic contaminants. These tablets also contain other proprietary additives to assist with water clarification and cleansing.

Active Oxygen is highly effective at killing bacteria and is used in a wide range of applications in the medical, food and water purification industries, for example, it is used for sanitising dentures and for water purification in developing countries.

eco3spa Step 3 - Multi-Function Water Sanitiser Tablets work synergistically with eco3spa Step 2 - Water Conditioner to keep your hot tub water clean and bacteria free.

Apart from the non-toxic environmental benefits of using Active Oxygen rather than Chlorine or Bromine, a further bonus is that Active Oxygen is an effective bactericide over a very wide pH range, so there is no longer any need to keep testing the water and using complicated water balancers.

Water that has been treated with eco3spa Step 3 - Multi-Function Water Sanitiser Tables is biodegradable, environmentally safe and may be discarded onto garden plants.
