Blanket Weed Controller
Several methods have been used to control the problem of blanket weed. Water-King is the original and best of the electronic blanket weed controllers. We do not claim to remove blanket weed completely, but simply to control it.

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.
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 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.
The Water-King needs no maintenance or servicing but do check occasionally to see that the light is flashing.
