Hello
i'm in the process of building a koi pond and would love some help in choosing an appropriate pump.
below some info about the pond.
gunnite circular pond, 6 feet deep. about 10000 gallons
two skimmers (4" pvc pipes below coping) at either side and a bottom drain Rhino II 4".
two aerators from the bottom. a 2 inch return pipe midway up the wall.
the two skimmers join just past the pond and a 4" pipe heads to the filtration shed.
the bottom drain 4 " pipe heads to the shed.
both are to be connected to a cyclone vortex 7500 system (gravity fed) after which i was going to have an external pump to pump the water back to the pond.
the filtration shed is 100 feet from the pond and the pump would be about 4 feet below the return pipe into the pond.
i'm a bit confused with the TDH calculations etc...
1. What brand would you recommend?
2. hp?
3. i assume high head?
4. 10000 GPH?
5. is the placement of the pump correct after the filtration system?
i really would appreciate any help i can get.
i thank you all
