Less than 0.5% of customers have reported poor or negative results using the Water Wych. Of these, most were due entirely to consistently high pH levels in the water. Reducing the level to pH8.0 or less has resulted in the Water Wych becoming totally effective.

Other causes of poor results were due to:

1. the pond or water feature being heavily shaded throughout most of the day. While the Water Wych itself does not require direct sunlight to work and can be safely placed in a dark or shaded part of the pond or water feature, sunlight on the water is important to the effectiveness of the Water Wych in controlling the growth of algae.

2. the Water Wych being placed in a water body with a constant throughput of new water, e.g. one fed by a stream or constant water changes from the tap.

3. the wrong size Water Wych being used for size of water body.

4. non-removal of the packaging in which it was purchased!

5. an excess of birds particularly pigeons using the pond as a bird bath.  The waste products from these birds increases the amount of nitrogen in the water to an amount the Water Wych finds hard to deal with.
