Your Pond Project – Planned Right, Built with Confidence
Planning, System Sizing and Project Support for Your Pond
Most pond projects don’t fail because of poor craftsmanship, but due to incorrect planning, undersized filtration systems, and a lack of experience in balancing hydraulics, technology and biology. This is exactly where koikichi.ch comes in.
Koi · Natural/Biotope · Fish · Swimming Ponds
You decide what you want to do yourself.
Proper system sizing instead of guesswork.
This Is for You If …
- You are planning to build a koi, fish, natural or swimming pond from scratch.
- You already have a pond and want to upgrade or optimise it (filtration, flow, water quality).
- You want a system that truly works reliably – not one that just “gets by”.
- You want to build it right once and avoid costly mistakes and unnecessary purchases.
- You want to decide how involved you are: DIY with expert guidance or full-service implementation.

Experience from Previous Pond Projects
Whether it’s a new build or an optimisation project – these testimonials show why clear planning and precise system sizing make all the difference.
“I wanted to upgrade my existing koi pond but had serious doubts about filter size and water circulation. The planning from koikichi.ch clearly showed me what I could do myself and where things become critical. The upgrade went smoothly – and the water is clearer than ever.”
Koi Pond Upgrade
Bern Region · DIY with Project Guidance
“When building our swimming pond, we wanted to avoid any experimentation. The differences between a swimming pond and a natural pond only became truly clear during the planning phase. Looking back, that was crucial – without this level of system sizing, we would definitely have had to retrofit later.”
Swimming Pond New Build
Zurich · Planning + Partial Implementation
“We already had a natural pond but were constantly dealing with cloudy water. Instead of selling new products, the entire system was analysed first. The solution wasn’t a complete rebuild, but targeted optimisation. Filter replaced, pumps repositioned – problem solved.”

Frequently Asked Questions
Is the enquiry really non-binding?
Yes. You first receive orientation and a clear proposal for the next steps. Only after that do you decide whether you want to go DIY, outsource selected parts, or choose full service.
Why is system sizing so different for koi ponds, natural ponds and swimming ponds?
The goals are different: koi ponds typically require higher hygiene standards, stronger filtration and clearly defined hydraulics; natural ponds and biotopes rely more on plant balance and biological processes; swimming ponds must additionally meet bathing and hygiene requirements. This is why “standard filters” are often the wrong choice.
I want to do DIY, but I’m concerned about technology and installation – is this still a good fit?
This is exactly what the model is designed for. You receive a clear step-by-step structure and ongoing support. The goal is to enable DIY implementation without costly mistakes. If needed, additional on-site support or installation services by koikichi.ch are available and can be booked separately.
What budget range do filtration systems typically fall into?
Many projects fall in the range of approximately CHF 5,000 up to the high five-figure range, depending on pond type and starting conditions, size, stocking levels, objectives and technical standards. Proper planning helps align budget and results.
