The ultrasonic transducer emits sound waves that tear apart the vacuole (a microscopically small blister inside the algae cell that houses the life functions) and the existing algae die as a result. Thereafter the transducer works as a preventative tool and stops the algae from returning.
There exist at least twenty thousand kinds of algae, which react in various ways after their demise. The most common algae are the so-called “roaming algae, which are brought into the water by wind and rain and which will be killed the most quickly - within a day or two. Others might last a couple of weeks, but will be dead in due time. Even though some algae die rather quickly, it may take up to 6 weeks before the effects are visible with the naked eye.
This depends on the application, in other words, the type of water body the Algae Controller is being used in. In swimming pools for example, the toughest ones are the black algae which mostly grow in the joints of the tiles. These will be killed eventually over a period of time. .Another hard type is filamentous algae. Some patience is definitely required here, as they knit together like a curtain which hinders the ultrasonic vibrations from penetrating the water properly. But they will die and can then be easily removed from the water.This has to be done regularly until all algae are killed and the water is cleared.
Of course this is not the case, it only LOOKS that way! There are two reasons why it appears like that:
This is highly recommended as the cost of electric power is very little. The VoR ALGAE CONTROLLER XXL uses 80 Watts. By having the ultrasonic vibrations permanently operating in your water, new algal blooms are prevented.
Preferably not! It is always best to either lengthen the electricity cable or bring the electricity source closer to the water body. When both options are impossible, it can be done, but ONLY with a cable made to the needed measurement, which you can order from VoR. This cable will have the right connecting plugs fitting to the electronics box and the transducer cable. Be aware: this connection is only drip waterproof, under no circumstances can it be used under water!
Also a mounted cable to the required length can be supplied on ordering the device. Lengthening the cable will cause some loss of strength of the signal.
Yes, no problem. Better if the cable has to be shorter to cut it to the required length and fit the original plug again, than roll it, as from this induction might influence the strength of the signal.
From where the 180 degree beamed waves from the front of the transducer cover as much of the water mass as possible, about 20 cm under the surface and not less than 20 cm from the bottom.This means that usually the best position is in a corner facing out. The VoR ALGAE CONTROLLER is equipped with a specially designed float, which keeps the transducer permanently on the right depth underwater.
When the red control light on the electronic box is blinking (4 seconds on, 1 second off), it means that the ultrasonic sound is produced. To check whether the transducer is working, you can hear an interrupted high tone when putting the front of the transducer to your forehead (do not be afraid, it is guaranteed non harmful).
If the transducer has already been in the water for some time and in front of it in the middle there is a clean round spot, it means that any growth of algae or other micro-organisms can not settle on that part of the transducer, showing it is working alright, killing and loosening all unwanted growth.
