In spring 2013 we shall be launching the NEW advanced PondTec range of ultrasonic units. Not only will these units be more powerful and therefore even more effective at controlling algae, but they incorporate new ‘Smart Scanning‘  technology.

There will be four models available, with effective ranges from 10m with the smallest up to 250m with the largest, giving a coverage of 31,250 sq metres.

Smart Scanning technology ensures that the signals sent to the transducer are optimised to transducer’s peak frequencies, ensuring optimum performance.

A 2012 trial with one of the prototype units, demonstrated just how effective these new units are.

Whitmore Fisheries near Blackpool has had a problem with the blue-green algae Oscillatoria sp for a number of years and in 2011 a PondTec 50 units was installed in the ‘East Lake’. The algae was controlled to some extent but could not be eradicated.

 On June 13th 2012 we installed one of the advanced PondTec units.

Below is a view of the lake

Within 2 weeks, the changes were already evident as the algae started to die off and the water colour changed.

June 21st and the algae has started to die off.

The PondTec unit was removed on July 3rd  July, to confirm that the ultrasound has killed off the algae.

East Lake on July 5th 2012 – water has now turned brown

On July 14th, we visited the site – the transformation is striking.

July 14th. For the first time in many years, no algae.

The dead algae has floated to surface producing the scum that is evident.

Please Note: As algae is killed off, oxygen levels will drop significantly so it is essential that adequate aeration is available to prevent any loss of fish.
