Backyard Aquaponics
A place to discuss aquaponics

I have a pond that is cement. 8 foot by 20 foot approximately 3 foot deep. Holds approximately 14,500 liters of water. I raise catfish in this pond plus use the water for my GB's. I want to change from using a pump in the water to an above ground pump. Problem is - I know nothing about above ground pumps. Is an above ground pump for fish pond the same as the pump one uses with a water tank for house use?

At the present time I pump water from the pond with a pump in the water. The water is pumped into a 6" dia. manifold that is 4 feet long. The manifold has four outlets. One to GB's, one to let water flow back into pond, one to solids filter, and one to a garden hose. I have no sump. Since I always have too many fish I water my dirt garden with pond water and refill when it rains, sometimes using tap water. This helps keep my water from getting too dirty. I would like to pump the water from pond directly into manifold as I do now.

All help and comments are welcome. Thank you.

Any inline pump should do as long as it is rated for continuous use, the type used on water tanks for houses is likely not continuous use and will burn out quicker, i think they also tend to be pressure pumps (?) which isnt needed.
a pressure pump will use more power for less volume.

if you can find a pond pump (maybe even the one you are using) that can have the front strainer taken off and used inline, then tat is all you will need. however these pumps still cant be used above the water line, so might need to dig a small ditch to put it in.

i think there are self priming inline pumps for above waterline use, but they are likely rarer and more expensive.


i would try changing the setup so your pond water that you water the garden with comes from whatever sort of swirl/radial etc, filter you use rather than straight from the pond, that way they get maximum nutrients with less water use, the fish pond also effectively gets a clean at the same time.

I'm wondering why you feel you need to switch pumps?

The pump I have is a larger pond pump and it can be set up as in the pond or "above ground" From what I've read, in the pond is more efficient.
