As professionals who've raised thousands of koi on our 3 million gallon koi farm, we know a thing or two about maintaining large ponds.
We highly recommend the Koi Keep systems because of their ability to maintain 5,000 and 10,000 gallon ponds.
There’s no better filtration system out there for large ponds like the Koi Keep. It even includes the Alpha One, a filter that can run for long periods of time (a month).
Coming from decades of experience maintaining large ponds, we feel the Koi Keeper truly makes managing your large pond a smooth and easy process.
