Always a pleasure to go to Champion Nishikigoi to pick up koi food for our koi pond. The staff is friendly and helpful. They always load the heavy bags of koi food in my car.

PondMax BactiMAX+ is a liquid beneficial bacteria treatment that digests fish waste, suspended dead organics and the excess nutrients that feed algae. It supports the ammonia and nitrite conversion your biological filter is doing, rather than replacing it.
Dosage
- 1 oz per 1,000 gallons, every two weeks.
- Double the dose for the initial treatment, or when restarting a filter in spring, to seed it quickly.
- Apply directly into the filter where possible, otherwise into the area of the pond with the strongest circulation.
Coverage: 16 oz treats 16,000 gallons · 32 oz 32,000 gallons · 1 gallon 128,000 gallons — each figure being a season's worth of fortnightly doses, not a single application.
Conditions
- Use when water is above 45°F. Below that the bacteria are not active enough to be worth dosing.
- Optimal range: pH 6.5–8.5, dissolved oxygen 5 ppm.

Excellent selection of high-quality imported Japanese koi. Everyone at the shop is friendly, knowledgeable, and patient, which makes the experience even better. The owner, Tom, is highly respected among serious koi enthusiasts across the country, and for good reason. His expertise and dedication to the hobby are evident in the quality of the fish and the service provided. Highly recommend!

My review comes with a bad experience turned immensely positive by the hard working staff at Champion Nishikigoi. I had spent a number of weeks debating on, and finally ordering a Showa upwards of 1k as the jewel of my collection. After purchasing the fish, I was notified that the fish was not in the pond and that it was possible that it was purchased in person earlier that day or that the listing had been updated without the initial listing having been removed. This was extremely disappointing to me. However, the team at Champion Koi personally reached out and the owner made recommendations for replacement. They provided me with a discount on the replacement fish, but more importantly, they actually listened to my concerns and my dismay at the experience. Champion Koi made real observable change as a response updating their website to include a warning about this very rare occurrence and making a guarantee of a 10% credit for anyone who would have a similar experience. It is extremely rare to find a business that cares enough to make actual change based on a customer experience and show that they actually care about their customers. They have certainly earned my business and they should definitely have yours!

Noy was extremely helpful and eliminated all my concerns/worries about ordering online considering I don't live close(Ohio). My gorgeous fish came looking exactly what I was expecting exceeding expectations! I'll definitely be ordering again.
