Here is some basic chemistry if you are interested. As you can see the active in Acquasafe (hydrogen peroxide or H2 O2) is just water (H2 O) with an extra oxygen atom attached. If normal hydrogen peroxide is added to water it quickly breaks down into water and oxygen. The hydrogen peroxide in Acquasafe does exactly the same thing but much more slowly because it is stabilised with Sanosil. This means this active ingredient works for up to two months to neutralise bacteria and viruses. Leaving your water improved when it breaks down into water and oxygen.
Acquasafe protects your family for as little as $2 per thousand litres of tank water.
