Koi Treatment with Heat Therapy

Koi are not truly a cold water species. Although they can live in very cold water, their metabolism functions better when the water temperature is near 76 degrees Fahrenheit. Koi's immune system is very slow below 65 degrees Fahrenheit. Many Koi ponds throughout the world never reach prime temperature for Koi.

BASIC KOI POND DESIGN

KOI POND DESIGN -- This article is a compiation of many koi experts' and enthusiasts' views, with an intermingling of my own views. . Besides collecting data from amny issues of KOI USA and Rinko Magazines, there is reference to Tetra's Koi Encyclopedia and heavy emphasis on Grant Fujita's book. My main goal is to give the koi hobbyist the foundation of what both a Basic beginner's pond as well as an ideal Koi  pond should contain. Realizing that not everyone has the space, money, nor ambition to do all that is mentioned in my paper for the Ideal Koi Pond. I at least try to emphasize those things that every koi pond should have to both minimize the maintenance and, even more importantly, to improve the health and quality of their koi.

Green Water Problem

Green water in the koi pond is the scourge of outdoor pond owners. Green water is caused by a population explosion of algae in the koi pond. Algae are microscopic, single-celled plants, which can easily multiply to a density of as much as 7,000-15,000 per milliliter. With that many of them in the water, it's no wonder that the water turns green. Koi ponds can get high concentrations of phosphates from food decomposition, and nitrates from the nitrification cycle. High concentrations of phosphates and nitrates are the food for pond algae, along with some iron as a catalyst. So high ammonia in the koi pond will make koi pond green.
