chilidog Posted September 2, 2018 Share Posted September 2, 2018 Hello, I was looking for any information on low cost aeration systems. I do not want paddle wheels more of the DYI compressed air ideas. I read somewhere that someone had used the idea from Nam Sai farms, but I can not find any information. Thanks for your help Link to comment Share on other sites More sharing options...
IsaanAussie Posted September 3, 2018 Share Posted September 3, 2018 I use my 3" sullage pump and hoses in a pond of about 600sq metres. The water output does a good job of aerating the surface with 4-5000 litres per hour. Of course the water is aerated by the pump and hoses as well. I can move the pump and hoses around the pond. If you have a pump and hoses, give it a try. Just the cost of running the pump. Link to comment Share on other sites More sharing options...

chilidog Posted September 4, 2018 Author Share Posted September 4, 2018 At the moment I am using 100 watt pump made by Mitsubishi so it is a oil filled sump pump. My idea is that if I can suck from the bottom and put it on top it would aerate the pond as well as get the ammonia to the top to evaporate off. It runs for 5 hours a day and I have grid tie in solar panels to off set the power usage. I plan on bringing in 7 more ponds and was wandering if what I am doing is the best option for multiple ponds. I did resurch using a side channel blower system but the expense of setting it up is up there. I also understand the risk of running and oil filled sump pump and am ok with it. I was more interested in different ideas that would work well and not use as much power. Link to comment Share on other sites More sharing options...
Thian Posted September 7, 2018 Share Posted September 7, 2018 i would use a floating solarpanel connected to an airpump and a bubblestone Link to comment Share on other sites More sharing options...
chilidog Posted September 8, 2018 Author Share Posted September 8, 2018 I have 18, 330w solar panels to a 5k inverter installed to off set the electric side and another 10 to install later. I did investigate using solar pumps and found I would be better off in the long run with a grid tie in system than each pump have its own solar panel. The other thing is with an air stone in a 20x20x1 meter pond would not be sufficient water movement. The idea is to get the stuff off the bottom to the top when you have aquatic animals that produce a lot of ammonia. Link to comment Share on other sites More sharing options...
