Lifecycle

Aquatabs have a five year shelf-life in strip packs and a three year shelf-life in tubs. All tablet products should be protected from exposure to temperature extremes or high humidity. The solution can be kept for 7 days in any sealed container or spray bottle, 24 hours in an open container or bucket.

Manufacturer Specified Performance Parameters

Aquatabs are designed to kill bacteria, viruses, and cysts in water.

Vetted Performance Status

The Aquatabs website states that Efficacy and Acceptability studies have been conducted in several countries throughout the world. This includes independent field trials in a wide range of waters (pH, turbidity, hardness, pathogenic challenge). The website reports successful comparative test trials and provides examples of studies undertaken.

Safety

Aquatabs should be used with clear water. If the water to be treated is murky / turbid, then it should be firstly filtered through a cloth until clear. If the water to be treated is being consumed from a known source (such as with a household water supply), then the low risk dosing, as shown above, can be used. In all other situations, then the high risk dosing should be used.

Complementary Technical Systems

Water requires prior filtration (through a clean cloth or filtering system) before Aquatab use.
