The Water Wych does not need any device to make it work. However, if placed in a pond with a pump and existing filter, it will work even faster! Simply immerse the whole unit in the water and let the magic do it's work! To obtain the best results from your Water Wych the water in your pond or water feature should be always maintained at levels below pH 8.0. Of the few customers who have reported poor results using the Water Wych, it was due to consistently high alkalinity levels - pH 8.5 and above.
Reduction of the alkalinity to a level of pH 8.0 or lower results in the Water Wych becoming totally effective within a few days. Then, within 2 to 4 weeks, the water will become as clear as a mountain stream! The Water Wych needs no maintenance. Once the contents have been saturated, remove it and replace with a new one. The contents of the saturated unit are 98% recyclable.
For best results, the Water Wych should be replaced every 6 to 9 months to ensure algae-free water at all times.
