Too much organic sludge build-up can produce a filthy odor Methods of Pond Dredging Mechanical Dredging There is likely a substance imbalance or build-up of waste causing the problem. If you find your pond water smelling unpleasant, the harmful byproducts that create when organic matter decomposes have reached a critical level. Such dirty water negatively affects the fish as well as the surrounding areas. When the water takes longer than usual to clear after a heavy rain, it’s a sure sign that the pond needs dredging. Brown pond water is a sign of low water depth in the pond Low Water Transparencyĭirty or murky water is another sign that the sediment at the bottom of the pond needs to be removed. The increased phosphate levels that are created when organic matter starts decaying will start a chain reaction of plant and algae growth that cannot be reversed by any other means effectively other than dredging. When the entire pond starts to grow more weed, it’s time to dredge it. You can clearly see excessive aquatic weed growth in the shallow area. Emergent pond plants are a clear sign of shallow depth. If too many emergent pondweed growths are noticeable then it is a clear sign that the pond has lost its depth. If your pond needs dredging, then you will see the following signs – Excessive Weed Growth Are There Any Disadvantages of Dredging A Pond. In most cases a trash pump can run a suction nozzle but not a jet. Not to be confused with a suction nozzle that most highbankers use that pushes material through the hose The impellor to the pump housing, and will not tolerate trash being put through itĪ trash pump can not and will not create the pressure a jet log (suction jet) utilizes to create a vacuume to lift material up the suction hose Where as a centrifugal pump has a very tight tolerance. Some trash pumps don't use impellors, if they do it's a very loose tolerance The 2 big differences between a trash and a centrifugal pumpĪs Walter says, a trash pump will allow a certain amount of small 'trash' (rocks, sticks, sand, twigs) to pass through without damaging the impellor or internals
