GC Tek KoiExerciser · 4-gang eductor tree

Turn the pond into a river

Carp are river fish. Koi that never swim against current lose their shape and grow big bellies — and body shape is the first thing a judge looks at. The KoiExerciser eductor tree takes the flow from a pump and multiplies it: each eductor entrains 4–5 times the water actually pumped through it, so a modest pump produces a strong directional current. Put it on a timer for a session or two a day and the koi will line up to swim against it. This is the 4-gang eductor tree only; add your own 1 HP pump and timer, or ask us about the complete kit.
