The Pulsar 4000 is the latest generation of ultrasound systems designed to manage algae blooms in ponds and lagoons. It's perfect for larger ponds and lakes on golf courses, commercial properties, waste water lagoons, and recreational water bodies. For the more dense filamentous algae, coverage range would be about 17 acres, with blue green algae, the range would increase to 120 acres.
It's coverage area provides 360 degree protection of most filamentous and single cell algae species using over 2000 targeted frequencies.
This density of very specific frequencies makes it a safe, non-chemical way, to manage most algae problems.
The unfortunate truth in managing large ponds and lakes is that the larger the water body, the more expensive it can be to treat. In many cases, algaecides are recommended to treat an algae problem and while they can work in the short term, the fact is, the cost of routine use of an "additive" can well, add up quickly.
It has not been uncommon for us to hear about 30 to 50 acre lakes being treated with copper algaecides to the tune of $50,000 per year! Keep in mind, dosage rates and the frequency of use will factor in here, but in cases where an algaecide is being routinely used, it may make more sense to consider ultrasound. Where a one time cost of the equipment could pay for itself in just a few months time.
This is why we also consider ultrasonic algae control as a possible option in an pond or lake of appreciable size, and particularly one that's requiring regular treatments with algaecides.
The Pulsar 4000 is safe for fish. Keep in mind, ultrasound technology is not a new thing. We've been working with it for almost 15 years now, and early on we tested the algae treatment approach to make sure it was safe for fish. In fact in those early years, we would use them in Koi ponds of various sizes and currently they are used in various aquaculture operations to help manage algae safely, without harm to fish or other aquatic critters.
Ultrasound systems have had one minor but annoying problem. Since the transducers heat up a bit while in operation, this heat attracts mineral deposits that are in the water. These deposits can eventually coat the transducer face and limit the output of the device. Wiper systems have been used with limited success to try to combat the issue but the Pulsar takes managing this problem a good bit further.
Each Pulsar uses an anti-fouling, anti-adhesion covering called Sharklet™, which inhibits mineral deposits from sticking to the transducer. As well, the Pulsar has a dozen cooling disks on the transducer to help dissipate heat off the head. These two advances will greatly reduce the hassle and need to clean the device on a routine basis.
Pulsar Ultrasound Systems are extremely energy efficient. A yearly cost to operate in most locations would typically be less than $50 per year. Standard systems use a land based power supply and a water proof power cable with lengths ranging from 5 meters up to 120 meters. Since the transducers emit sound waves in a full 360 degree pattern, center placement in a pond or lake is best for coverage, although not always required in smaller ponds.
For larger lakes, the device can be powered with a solar float platform. Optional telemetry packages are also available with the solar float and included monitoring for system operations as well as water quality parameters.
The Pulsar comes with a 3 year warranty.
*Specific ranges (radially from the transducer) for the Pulsar 4000 are 60 meters for biofilm, 150 meters for filamentous algae, and 400 meters for blue-green algae.
