These comprehensive kits provides efficient aeration, promoting a thriving aquatic ecosystem by increasing oxygen levels and breaking down waste. Designed for ponds and lakes up to 6 acres, these system delivers reliable performance and long-lasting durability. The Important of Subsurface Aeration The Important of Subsurface Aeration The aeration of ponds and lakes is a vital factor regarding the health of your feature. Dissolved oxygen is imperative for a healthy feature and to prevent pond and lake turnovers and promotes fish health. Secondly, all ponds or lakes deeper than 6-7 feet will have a thermocline - a separation of cooler water on the bottom level below the thermocline containing poor oxygen levels, high in methane, hydrogen sulfide and other gases; and the top layer which is warmer and contains most of the oxygen. Bottom aeration breaks this thermocline up to mix the water together providing oxygen to all the water by breaking the thermocline and diffusing the gases to the surface for evaporation through osmosis. Bottom aeration should be started slowly at an hour a day and steadily increasing an hour a day during daylight hours until the pond aerator is on 24 hours to prevent instant turnover and mixing of gases. Pond or lake turnover happens naturally and will happen eventually in every pond - it is just a matter of time, not if, but when. Therefore, bottom aeration is so very important for fish health. Large ponds and lakes naturally aerate through plant photosynthesis and atmospheric mixing like wind and rain. The problem is that most ponds and lakes do not absorb or receive enough oxygen compared to how much is being used and this harms the aquatic system. All life in the ponds or lakes needs oxygen to be healthy and prevent pond or lake turnover: the disruption of thermocline - the separation of upper levels of water and lower levels which then mixes gases, nutrients like phosphorous and nitrogen, into the oxygen rich surface water, suffocating the wildlife within 24 hours or so. The bottom aeration can work up to 40 feet or so without adding to much pressure back on the motor - psi. Bottom aeration should be used in conjunction with beneficial biologicals except in the case of an ongoing fish loss. Beneficial Pond starter can be added once the pond or lake has adequate oxygen supplied for several weeks. The benefits of bottom aeration are many - more oxygen for healthy water, no thermocline which removes the chances of lake turnover, healthier fish, healthier pond and keeps a hole open in the ice for gases to escape in winter as well as allowing animals to drink depending on placement of diffuser. Half Off Ponds Pro Deep Water Subsurface Aeration System Half Off Ponds Aeration Compressors are high flow, high capacity air compressors ideally suited for lake and pond bottom aeration. Half Off Ponds, Pond Air Compressors operate on a 120-volts with a 6-foot double insulated power cord and are most efficient in 25-foot water depths, with a maximum operating depth of 40 feet. Air filter with replaceable, debris-trapping element delivers clean, pure air. These reliable, low maintenance units are designed for continuous or intermittent operation. Sealed connecting rod and bearing lubrication, oil-free air compressing chamber and shock-absorbing vibration-isolating mounts assure years of trouble-free operation on the Pond Air Compressor. The Aeration Compressor is used to circulate water and allow gasses to harmlessly escape as well as help prevent the pond surface from freezing over in the winter months. Hand-selected components are durable, reliable, and low-maintenance. Half Off Ponds Pro Deep Water Subsurface Aeration System delivers oxygen to create and maintain a healthy environment.
