fish farming Pond aireation questions

Recommended Posts

I wanted to share an update on what I learned and ended up doing about my aeration questions. I ended up installing an .8KW (1HP) ring blower. It is connected to a 2" pipe that is running to 2  20x20 ponds and I have 6 air defuser in each pond and the ponds are lined with plastic. I will experiment with stocking densities of pla duk and crayfish mono-culture. It might sound a bit too much air but I have my reasons to set it up this way. With the amount of air the blower puts out I could have 10 normal 20x20 ponds the same size and keep the DO at a good level.

Yes the pump will be running 24/7. For what i am trying to accomplish it will need to be. I have'nt had it running a month just yet but my guess is it will cost around 1,700baht a month. It should use 19KW a day and my solar panels make 15KW to 26KW a day. I plan on installing one more blower the same size for 2 more ponds.
