Controlling Algae in Ponds and Lakes with PondTec Ultrasound
Ultrasound is a very effective method of controlling algae in ponds and lakes, the PondTec ultrasound units are easy to install, cheap to run (40 watts max) and will deal with most algal species. If you have weed problem, ultrasound is not an option for you, as it has no effect on submerged plants (macrophytes).
The PondTec units have coverage ranging from just 12.5m² for the smallest PondTec 05 to 12,000m² for the largest PondTec 50 model. All you require is a power supply.Normally the units run on 230-240V AC, however we can supply units which run on either 12 or 24v DC, which can be powered either by a battery or a battery/solar panel combination.

The algal species growing in lakes and ponds varies throughout the season – starting and finishing with with diatoms, to be followed by the green algae and then the blue-green algae.
The diatoms bloom early in the spring and then die back, only return later on in the autumn.
Algal growth is totally dependant on nutrients such as nitrates and phosphates and if they are in abundance then the algae will THRIVE! If you have an algal problem, you know where to look.
To remove excess nutrients from a lake, you will either have to remove the excess silt (expensive!) or add products which ‘bind’ the excess nutrients, however they are not removed and bacterial action will ensure that they return into the water, a process that will be speeded up if you have fish grubbing about in the silt for food.
The sensible alternative is to install a PondTec ultrasound unit. Once installed and switched on – that’s it. Simple
The ultrasound unit is left on continually, however during the winter months you can put the unit on a timer so that it only comes on for a few hours during the day- this just keeps the algae in check.
The PondTec units will deal with most algae, however there are some stubborn ones which are unaffected, primarily green algal species, so take a look at the algae section.
One of the most annoying types of algae is blanket weed , besides being unattractive, it takes both and time and effort to remove from a pond, however ultrasound is very effective at killing it off. If a PondTec unit installed early on in the season, blanket weed won’t be able to become established. The images below, are before and after ultrasound treatment.
