About Koi Pond Calculators
Koi pond performance depends on the relationship between water volume, turnover rate, filtration, and energy usage. These calculators help you make informed choices before you buy pumps, filters, and plumbing.
Start with pond volume, then size your pump based on target turnover and estimated head loss. Using data-driven sizing early helps prevent water quality instability, underpowered circulation, and unnecessary operating costs.
