Foaming the Koi pond water to a lesser extent will disturb the view and reduce the beauty of the pond. The foam in the pool will usually be visible, especially those sticking to the edge of the pool. Even after cleaning, the foam will usually appear again. The foam in the pool is quite difficult to clean without special handling. In some cases, even replacing 3/4 of the pool water did not remove the foam. Also, the lack of dissolved oxygen levels contributes to the foam damage in the pool. Foam koi pond water; everyone, both small koi ponds and even large ponds. This foam certainly indicates that something is not right in your pool. Some other causes of foamy water are generally foam or foam in pool water due to high levels of Dissolved Organic Compound (DOC). DOC consists of being formed from leftover feed, feces, and fish urine dissolved in the air.
Another factor that can also cause a pool to become foamy is an increase in increase in CO2 levels in the air. One of the causes of the increase in CO2 levels is that a lot of plankton die at the same time. Apart from foam, high CO2 levels also affect the quality of the water to become cloudy and concentrated. The phenomenon of algae blooms can occur due to the excessive fertilization process in the pond or the use of plankton catalysts. Of course, this makes the algae population increase and out of control. More than the population of algae is what makes the pool foamy, besides that the pool water will also look more concentrated. Apart from the factors above, it turns out that foam can also appear during salting. Pond salting is usually done to stabilize the pH of the water after rain. Also, fish salt is often used for disease prevention treatment therapy. The effect of foam during salting is usually only temporary and will return to normal by itself.
Foam in pool water generally occurs due to a lack of dissolved oxygen in the air. Dissolved oxygen levels are physically in the form of fine air bubbles in the air pool. To increase dissolved oxygen levels, you can use an aerator or make a fountain or waterfall in a pool, the more dissolved oxygen levels, the better. Increase in oxygen levels with decreasing temperature in pool water.
