Adding New Fish To A Pond

All new ponds must go through a nitrification cycle before they are stocked. Koi fish may not survive in a pond that lacks sufficient levels of nitrifying bacteria.

A nitrification cycle should begin with only 2 Koi fish for a 1,200 gallon pond or 4 Koi fish for a 2,000 gallon pond. The process occurs when the pond water contains enough nitrifying bacteria to counteract organic waste and other bacteria found in fish ponds.

The appropriate number of Koi should be introduced into the pond at the same time. Additional livestock may be added to the pond 4 to 6 weeks from the start of the first nitrification cycle.
