Frequently Asked Questions

Is the plan really personalized?

Yes. The builder asks about your pond, your fish, your climate, and your current headaches, and the calendar, feeding guide, and action plans are built from those answers, not a generic template.

Do I have to join the membership?

No. The Pond Care Plan works as a one-time purchase with no ongoing charge. The Pond Care Calendar membership is an optional add-on for anyone who wants seasonal task reminders.

Can I cancel the membership?

Yes, anytime, from a self-serve billing link. No phone call or contact form required.

Are the free tools really free?

Yes. No signup, no trial, no credit card. They stay free whether or not you ever buy the plan.

What if the plan is not right for my pond?

Every purchase is covered by a 30-day money-back guarantee. Email support@koiquanta.com within 30 days and we will refund it in full, no forms or hoops.
