Velda introduces a revolutionary product which tackles the algae problem with lasting results.
The core of the I-Tronic consists of an anode made of a mineral copper alloy and a cathode of stainless steel. The operating unit, controlled by a microprocessor, generates electric pulses, releasing positively charged copper ions or minerals, which kill both fibrous and slimy algae in a natural way.
This effective and biologically friendly technique has been derived from space technology. The specific concentration of copper ions to remove fibrous algae and to stop their growth, ranges between 0.2 and 0.3 ppm. This concentration is absolutely safe for humans, animals and plants. For example, according to the European Drinking Water Directive, a concentration of 2 ppm is allowed in drinking water. In normal pond water, at a pH value of 7 or more, the above concentration will rarely exceed the value of 0.3 ppm, even if the I-Tronic were used continuously. So, the equipment is working safely both for flora and fauna in a pond, and yet the concentration it supplies is adequate to stop awkward growth of algae. As a result, your pond will be healthier and have a fresh, neutral odour.
