WATERKING for ponds
Model WK1PP Blanket Weed Controller With External Transformer
The original and still the world's best known Electronic Blanketweed Controller! We do not claim to remove blanket weed completely, but Water-King can control its growth so that it no longer causes a problem.
We also offer a No Quibble Money Back Guarantee

LOCATION
The unit can be fitted on pipes up to 50mm in diameter and should be installed as close as possible to the pipe. The unit will operate on any normal type of pipe material, including corrugated, plastic and BSP (waste pipe). The pipe to be treated must be full of water at all times which means that water must be flowing either under pressure or suction. A pump will cause electro-magnetic interference with the signals generated by the Water-King and installation immediately prior to a pump should be avoided. The optimum location is after the pump. The Water-King will also extend the life of the quartz sleeve in the U.V. system by keeping it free of scale deposits in hard water areas. |
A period of 7 to 8 weeks should be allowed from installation before the full effects of the Water-King may be seen.
HOW THE UNIT WORKS
Once the unit has been installed correctly on the pond system it will pass an electronic signal which will interfere with the calcium ions in the water. Blanket weed is a long filamentous structure and calcium plays an important role in the strength and structure of the membrane which is responsible for controlling the nutrient intake to the cell. The electronic signal will disrupt the equilibrium between the calcium present in the solution and the calcium in the cell membrane upsetting the cell metabolism. The membrane will have no means of preventing excess solution from entering or exiting the cell, and this means that the cell will either expand and explode, or shrink and die.
Initially the process will encourage growth and the weed will expand, but once the water reaches a "super" conditioned state, the weed will begin to die away. The Water-King will control the growth of the blanket weed although it may not remove it completely.
DO I NEED TO DO ANYTHING ELSE
It is important that you monitor the conditions of your pond water during this time as high nitrate levels and pH fluctuations will cause the blanket weed to continue to grow. This is especially important if your pond is constructed of concrete as lime may leach into the pond water and cause a variation in the pH level. We recommend that the nitrate level should be kept at around 25ppm or lower. It may be higher than this, depending upon the quality of the mains water and the filtration system installed on the pond. If you are in any doubt then contact us or seek advice from your local stockist.
We recommend that any dead or dying blanket weed is removed in order to prevent de-oxygenation and clogging of filters. Regular ammonia, nitrite and
nitrate tests should be carried out during this period. Ponds with excess amounts of decaying material can suffer from a disruption of the Nitrogen Cycle, so a water change may be required. It is also advisable to keep feeding down to a minimum. Uneaten food, as well as dead weed left in the pond will encourage the return of blanket weed. Blanket weed on a waterfall will take longer to be effected by the Water-King because of high light levels and oxygen.
In some situations blanket weed growth can increase within the first two to three weeks of operation. This excess growth will cease when the unit has "super" conditioned all of the pond water.
Technical Data
The WK1PP is tested to IP68 3 meters immersion depth and is therefore fully water proof. The aerials and power supply are directly wired and cannot be
removed from the unit whose circuit board is encapsulated in epoxy resin. It will not be affected by immersion, external weather or adverse damp conditions. The Water-King requires a 120 volt power outlet for the transformer. The transformer is rated for indoor use only and must not be allowed to get wet or damp, so it may be necessary to extend the low voltage power cable to an acceptable protected socket. Additional cable may be spliced into the existing lead between the transformer plug and its socket. A waterproof seal should be made over the connections. Avoid short circuiting the wires as this can cause the transformer to fail. Satisfactory tests have been conducted on a cable extension of 500 meters. As the low voltage supply is AC, there is no need to be concerned about polarity.
MAINTENANCE AND TROUBLE SHOOTING
The Water-King needs no maintenance or servicing but do check occasionally
to see that the light is flashing
