A clear, healthy pond is a routine, not luck
Whether your pond is actually big enough for the koi you want, or already overstocked. What your ammonia and nitrite read this week, and whether the nitrate is creeping up. When you last did a water change and how much you took out. Whether you should still be feeding now that the water is cooling. Whether the pond is truly ready for its first freeze. Any one of those is easy to lose track of. Together they are the difference between clear water and healthy koi, and the green water, sudden losses, and frustration that wear most pond owners down.
Koi hide stress until it is serious, so the small signals matter: a slow nitrate climb, a skipped water change, an overfed pond in cool weather, a sealed sheet of ice with no gas exchange. And the practical side adds up too, the gear you still need to buy, the seasonal tasks you keep meaning to do, the stocking plan you are holding together in your head.
This planner gives you one clear place to plan and track all of it, so you build it right, catch changes early, and always know exactly how your pond is doing.
What's inside
9 printable worksheets designed specifically for backyard pond owners, from the first dig to a dialed-in year-round routine.
Pond Build Planner
Plan dimensions, water volume, liner size, pump GPH, and a full build budget on paper before you dig. Get the gallons right once and every other worksheet, from stocking to dosing, falls into place.
Stocking Planner
List every koi and goldfish at its full adult size, with quantity, gallons per fish, and a running total, so you stock the pond you actually have and never overload it into murky, unhealthy water.
Water Test Log
Track temperature, pH, ammonia, nitrite, nitrate, and KH over the season in one place. Catching a slow nitrate climb or a pH swing early is the difference between a quick fix and a fish loss.
Seasonal Maintenance Schedule
A spring, summer, fall, and winter task checklist built around water temperature, not the calendar, so nothing critical slips between opening the pond and closing it down for winter.
Koi Health Log
Record symptoms, treatment, salt percentage, and outcome for each fish. A dated history helps you spot patterns, avoid repeating a treatment that failed, and brief a specialist if you need help.
Equipment Checklist
Pump, filter, UV clarifier, liner, skimmer, aerator, net, and test kit, with columns for what you own, the brand and model, and what is left to buy before fish go in.
Water Change Log
Log the date, percentage changed, gallons, and dechlorinator dose for every water change, so your most important routine stays consistent and ties straight back to your test results.
Feeding Log
Track food type, amount, and water temperature each day, with a built-in reminder to stop feeding below about 50F, so you never overfeed or feed koi that cannot digest in the cold.
Winterizing Checklist
A step-by-step plan for de-icer, aerator, netting, stopping feeding, and your pump, so your koi rest safely under the ice and come through to spring.

Frequently Asked Questions
What format are the planner pages in?
Every page is a standalone, print-optimized file plus one combined PDF. Open any worksheet in a browser, hit Print, and you get a clean, professionally formatted page sized for letter paper. No special software needed, and you can save any page as a PDF too.
Can I print the pages more than once?
Yes. Once you purchase, you can print every worksheet as many times as you need: a fresh water-test log each season, a new feeding log for the warm months, or extra copies for everyone who helps with the pond.
Is this a subscription?
No. It is a one-time purchase of $39. You get immediate access to all 9 printable worksheets and the full planner PDF, with no recurring charges, ever.
Will this work for a goldfish or water-garden pond, not just koi?
Yes. The worksheets cover the fundamentals every pond shares: volume, stocking, water testing, water changes, feeding, and the seasonal routine. Koi are the heaviest waste producers, so a planner built for koi gives goldfish and mixed ponds plenty of headroom.
Is this useful for a brand-new pond owner?
Absolutely. The build planner, equipment checklist, and stocking planner give first-time owners a clear path from an empty hole to a stocked, balanced pond, so nothing critical gets skipped. Experienced keepers use it to finally get a year-round routine organized in one place.
Why so much focus on water testing and winterizing?
Because they prevent the two most common causes of fish loss: ammonia or nitrite climbing unnoticed in a new or overstocked pond, and koi suffocating under a sealed-over sheet of ice. Regular testing catches water problems while they are still easy to fix, and the winterizing checklist keeps the pond safe through the cold.
