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.
