Extensive sludge buildup can cause periodic odor problems and algae blooms. To minimize odor and algae blooms it is important to keep the intake above the highest sludge level in the pond to slow down the rate of sludge digestion. If more control over odor or algae is necessary, a 24-hour auxiliary power kit or a chemical injection kit can be used. Each unit weighs about 275 lbs., excluding anchor. This design minimizes obstruction and turbulence from water exiting the distribution dish.
Tapered sides allow the entire machine to be encased in ice without damage.
Also, the floats are designed with sufficient buoyancy to allow maintenance on the unit if required. No, the standard Pond Doctor utilizes a specially designed electronic controller to ensure that it operates every day from sunup to sundown. Yes, but at a reduced circulation volume, however, overall effectiveness is unchanged. If the climate is severe or if site conditions warrant, an auxiliary power kit should be considered. The stainless steel impeller shaft is surrounded by an oil-filled Teflon tube, which allows the shaft to turn even though the tube is encased in ice.
