Koi Food & Pond Supplies
Healthy koi start with the right food, clean water, and reliable pond equipment. ChampKoi has supplied Japanese Nishikigoi keepers since 1998, and we stock the same food, treatments, and pond gear we use on our own holding systems in San Jose, California. Everything below is organized by what it does, so you can go straight to what your pond needs.
Koi Food
Feeding drives growth, color, and body conformation more than any other single factor. Match the food to the season and to what you want the fish to do — grow, hold color, or simply stay healthy through cooler water.

Koi Food by Brand
Koi Health & Water Quality
Most koi health problems trace back to water quality. Test first, treat second — and keep a basic treatment kit on hand before you need it.
- Koi medication & treatments — parasite, bacterial, and ulcer treatments
- Pond water treatments — dechlorinators, beneficial bacteria, salt, and conditioners
- Water test kits — ammonia, nitrite, nitrate, pH, and KH testing
- Pond algae control — string algae and green water solutions
Pond Equipment
Filtration and circulation carry the load in a koi pond. Koi are heavy waste producers, so size your filtration and aeration for the fish you plan to keep, not just the fish you have today.
- Pond filters & filter media — mechanical and biological filtration
- UV sterilizers & clarifiers — green water control and pathogen reduction
- Pond pumps — circulation and filter feed pumps
- Pond aeration — diffusers, air stones, and aeration kits
- Air pumps — complete aeration units
- Pond plumbing & valves — fittings, bulkheads, and flow control
- Pond covers & netting — leaf protection through fall and heron deterrence
- Pond liners & construction — liner and build materials
Replacement Parts & Accessories
Keep spares for the parts that wear: UV lamps, quartz sleeves, impellers, and seals. A failed UV bulb or impeller mid-summer is a water quality problem within days.
- Replacement parts — lamps, sleeves, impellers, and seals
- Aqua UV parts & accessories

Not Sure What You Need?
If you are setting up a new pond or troubleshooting a sick fish, start with a water test before buying treatments. Our koi care guides walk through the common issues, and you are welcome to contact us with your pond size, filtration, and test results for a specific recommendation.
