<\/span><\/p>\n If the koi pond water is white in color, test for ammonia, nitrite and dissolved oxygen. If ammonia is high, increase the amount of new water, and increase pumping or jetting. If nitrite is high and dissolved oxygen is low, clean out the filter tank without reducing the amount of water in the pond. When the color of water is yellow, the concentration of nitrate may be higher than<\/span>30mg\/kg<\/span>Above that, it is necessary to regenerate the zeolite immediately.<\/span><\/p>\n <\/span><\/p>\n When the color of the water is green, the dissolved oxygen varies greatly between day and night, and there is a danger of fish jumping out. When you get up in the morning and find that the fish are injured, it is often because the dissolved oxygen is reduced at night, and the fish feel uncomfortable and jump around, so be careful of the difference in dissolved oxygen between day and night due to the role of oxygen and carbon dioxide from algae. Pool water turns green, sometimes because the treatment pool is dirty and the dissolved oxygen is insufficient; or because the speed of treatment is too fast.<\/span>(<\/span>river<\/span>)<\/span>The dirt has not been treated but has been caused by the circulation. At this time to increase the pump's head is also one of the ways to solve the problem.<\/span><\/p>\n <\/span><\/p>\n <\/p>","protected":false},"excerpt":{"rendered":" When the color of koi pond water is white, test for ammonia, nitrite and dissolved oxygen.
