Frequently Asked Questions

What koi varieties does Genki Koi typically carry?
Local koi stores in San Jose often stock a rotating selection of popular varieties including Kohaku, Sanke, Showa, Butterfly koi, and Ogon. Availability changes as new fish come in, so it's worth calling ahead at (408) 295-4500 to ask what's currently in stock.
Can I get my pond water tested at a local koi store?
Many local fish stores offer in-store water testing where you bring in a small sample from your pond. Staff can check for issues like high ammonia, pH imbalance, or low oxygen levels and recommend specific treatments on the spot.
How do I acclimate new koi when I bring them home?
You should float the transport bag in your pond for 15 to 20 minutes to equalize temperature, then slowly add pond water to the bag over another 10 minutes before releasing the fish. Keeping new koi in a separate quarantine tank for two to four weeks before adding them to your main pond is strongly recommended.
Is San Jose's climate suitable for keeping koi outdoors year-round?
Yes, the Bay Area's mild winters make outdoor pond keeping very manageable in San Jose. Koi can typically stay in outdoor ponds year-round without the heaters or pond covers that colder climates require, though monitoring water temperature during brief cold snaps is still good practice.
What size pond do I need to keep koi?
A general rule is a minimum of 250 gallons per adult koi, but most experienced hobbyists recommend at least 1,000 gallons for a small group of fish. Larger ponds are more forgiving of water quality fluctuations and give koi room to grow to their full potential.
Do local koi stores offer advice on pond filtration?
Yes, staff at specialty koi stores can walk you through filtration options based on your pond size and fish load. Good filtration is one of the most important factors in koi health, and getting that guidance in person is one of the main advantages of shopping at a local store rather than ordering online.
