What koikichi.ch stands for
Advice that makes decisions easier – and solutions that work in everyday life.
Expertise that helps
We translate technology into decisions that work in everyday life – understandable, structured, and comprehensible.
Precisely fitted instead of arbitrary
Recommendations are based on the objective, framework conditions and practice – not on a “one-size-fits-all” approach.
Reliability
We will continue to support you even after your purchase – with questions, adjustments or useful optimization steps.
Pragmatic implementation
Whether DIY or project: We provide support where it brings you security, clarity and speed.
This is how we work
Good results are achieved when goals and parameters are clear first – and products are selected accordingly. That's why we proceed in a structured manner:
Understand
What is your goal, what resources are available, and what are the challenges?
Recommend
Product and solution proposals tailored to the situation – with clear justification.
Deliver
Selection from the shop so that you can reliably obtain the right components.
Support
Support, optimization, and, upon request, planning and implementation of construction projects.

Frequently Asked Questions
Do you also offer advice if I haven't bought anything yet?
Yes. Consultation is particularly useful before purchasing, in order to define a suitable solution and avoid making the wrong decision. Further, more complex tasks such as planning, analysis, or troubleshooting involve costs. Should this be the case, we will inform you before any costs are incurred and provide you with a transparent cost estimate.
Do you also support DIY projects?
Yes. If you'd like to take matters into your own hands, we'll provide targeted support where you need clarity – for example, with product selection, setup, or specific questions. Further services may incur additional costs. However, you will be informed of these in advance and will always retain full control.
Do you also handle the planning and implementation?
Yes. In addition to our shop and consulting services, we also offer support in the planning and implementation of construction or optimization projects – depending on the requirements.
Do you offer service and maintenance for pond equipment?
Yes. Pond maintenance is a key part of our services. We would be happy to assess your pond system individually. Please send us a brief message including your location, some photos of your existing pond, and a description of the work you require. Based on this information, we will provide you with a transparent cost estimate.
