## What is Koi Cal Pond Care + Health AI?

Keep track of your school in a beautiful way. Enter your pond info to keep your water clean and fish healthy.

Koi Cal helps koi owners keep track of every fish they own, diagnose pond problems, dial in feeding, and keep their water crystal clear. Build a profile for each koi, log a feeding, run a water test — and get a personalized Health Plan tuned to your fish, your weather, and your pond.

YOUR SCHOOL, ORGANIZED
• A profile for every koi: name, variety, birthdate, length
• Photo timeline per fish — watch them grow month by month
• AI-stylized portraits of your favorites
• iCloud sync keeps your school backed up across devices
• Sort by name, age, or most recently added

AI HEALTH PLAN
• Personalized feeding recommendations — how much, how often, what food
• Pond Report card — at-a-glance health overview
• Per-concern advice — fixes targeted at your exact problem, not generic forum tips
• Auto-adjusts to your local weather and water temperature

LOG WHAT MATTERS
• Daily feedings (up to 3/day) with food type
• Water tests: pH, KH, GH, nitrate, nitrite, salinity
• Pond setup: size, location, sunlight hours, circulation time
• Fish details: species, size, age group, count

WE CATCH PROBLEMS LIKE
• Cloudy, green, or dark water
• Inadequate circulation or filtration
• Overstocking and overfeeding
• Flukes and other parasites
• Low energy, hiding, or loss of appetite
• Out-of-range pH, nitrite, nitrate, KH, and GH
• Stunted growth and obesity

TRACK YOUR GOALS
Whether you want better color, faster growth, breeding success, or calmer behavior — Koi Cal tunes its recommendations to your goal.

WHY KOI CAL?
Most pond apps treat your fish as a number. Koi Cal treats them as individuals. Every koi gets a name, a photo timeline, and a place in your school — and the AI weighs your pond, your fish, and your weather together to give you one clear answer. Save your fish, save your weekend.

Built for backyard koi keepers, water garden hobbyists, and fish keepers of every level.

### 5/5 — VERY helpful for beginners

*2025-05-05*

I recently bought a home that has a Koi pine. I didn’t know how to care for it at all, and the water looked very dark. After generating a health plan and following basic instructions within a couple weeks the water was clear and the fish have been doing great for months.

### 5/5 — Koi & Pond Calendar
