Half Off Ponds Series Subsurface Air Pumps and Aeration Kits The Half Off Ponds Aeration Pumps are the perfect choice to create and maintain a healthy pond environment. These highly efficient, low energy pumps enhances oxygen levels and the turnover rate of the water in your water garden or fish pond. The aerator supplies oxygen to your water feature which keep your fish happy and healthy. During the hot summer months, the Patriot Air Pump's have an overload sensor that prevents the pump from burning out due to maintaining the needed oxygen levels to avoid oxygen-depleted water. The Half Off Ponds Air Pump Aeration Kit is used to circulate water and allowing natural gasses to harmlessly escape as well as helping prevent the pond surface from freezing over in the winter months by disrupting the water’s surface. This is the perfect aerator to maintain and keep a healthy water feature. Turnover is very important; moving water from the bottom to the surface reduces thermal layering and helps bring debris into suspension so the filtration system can remove and treat it. 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 fish loss. 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 natural 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. Fish loss during a lake or pond turnover can happen overnight. Therefore, bottom aeration is so very important. 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. The bottom aeration can work up to 40 feet or so without adding too much pressure back on the motor - psi. Bottom aeration should be used in conjunction with 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. Aeration decreases the chances of lake turnover and promotes healthier fish Aeration makes a healthier pond and keeps a hole open in the ice for gases to escape in winter as well as allowing water fowl and other animals to drink depending on placement of diffuser.

  • great service
This product is working well in our pond. It's been installed for about 6 months now and the pond is much clearer and the pump is quiet and works well. The first pump I received was damaged in shipping but the return was fast and easy and the company issued a prompt refund and I ordered again. Great product and great customer service. ... show more

  • Missing or wrong fittings
The unit seems well constructed and the aeration stones are of a good quality. The issue is: The single connection exiting the unit is 5/8. The hose is 3/8. The distribution fitting is for 1/8 tubes. The only way I can hook it up is to have all the aeration stones in tandem. (one after the other on the same line) I don't know the exact math but I suspect if all four aeration stones are connected to one 3/8 line I will get about half the total air intended to be delivered to the diffusers. Is that correct or is my gpm flow rates for 3/8 compared to 5/8 incorrect? ... show more

  • Will purchase another one soon!
I was a little skeptical after reading some of the reviews on other Patriot Aeration systems. Especially since there were none on this specific model. Pros; The price CAN NOT be beat! It works GREAT! The diffusers are very well made! The pump is VERY quiet!!!! Con; The manifold and clamps were very cheap and were also the wrong size. So we are only able to run one air hose line. We will be purchasing another one VERY soon for more aeration!!! ... show more

  • Lasted 2 days
The pump ran for two days, started rattling and then it stopped working. The fittings that go on the aerator discs are for a 1/2" hose. The do not fit the included hose and will come off. You can order the correct ones on Amazon, you'll need brass 1/8" male to 5/8" ID barb. Overall, I think the quality of the kit is pretty good. It seemed like the pump did put out a good amount of air. I'm no lake/pond aeration expert, so you'll have to consider if this will work for your application. I spent hours setting this up, only to have it break. Now I have to pay for return shipping for a heavy box and they may charge a 15% re-stocking fee. Thanks for that. ... show more

  • excellent pump
I bought the pump for my pond. When I started to assemble it, I realized that a small connector hose was an elbow shape and not a straight piece as it should have been (the elbow would have caused the airflow to be restricted and cause the pump to overheat). I called the manufacturer and spoke to Mitchell. We verified that I did receive the wrong piece and he is sending the correct one. He was incredibly helpful and knowledgeable and answered all of my questions easily. He is also going to send recommended hose length for each of the 4 diffusers. The pump itself and all the parts are very well constructed and I do not feel like it was over priced for the quality. ... show more

  • Works great at a depth of eight feet.
The product produces plenty of air. The diffusers make lots of small bubbles. It could be much quieter. The unit I have rattles like the housing is loose. No amount of tightening stops the rattle.
