Color Changes in Koi Pond Water and Disposal Methods

When the color of the water is white, test for ammonia, nitrite and dissolved oxygen. If ammonia is high, quickly increase the amount of new water, strengthen the pumping or jetting. If the nitrite is high and the dissolved oxygen is low, it is necessary to clean the filter pool without reducing a lot of pool water.

The concentration of nitrate may be higher when the color of the water is yellow than30mg/kgAbove that, it is necessary to regenerate the zeolite immediately.

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.(river)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.
