Foam on the water surface of the fish tank indicates that the water quality is not good. Generally, it is due to eutrophication. This kind of water can easily lead to the outbreak of algae. It can also promote the reproduction of microorganisms and increase the content of ammonia nitrogen in the water body. This will cause harm to the fish. Therefore, it is necessary to change the water in time.Usually change the water to change a quarter, change too much, then easy to stimulate the fish.
For water problems, the simplest way is to strengthen filtration, filtration equipment as long as the normal operation, water quality can be maintained.If the fish tank and filter equipment are not equipped, it will take too long to filter once, or too many fish will affect the efficiency of filtration, which requires a higher power filter.
Usually there are bubbles in the fish tank, indicating eutrophication of the water body. This is mainly caused by feeding too much at ordinary times. After the residual bait and fish feces are decomposed, a large number of bubbles are produced.Want to avoid this situation, the best way is to reduce feeding, feeding 1-2 times a day, each feeding to 78 points full can be.
When the fish are in the breeding period, the female fish will produce eggs. Because there is no male fish fertilization, these eggs will not hatch, but will slowly rot in the water, resulting in bubbles on the water surface, affecting the health of the fish.Therefore, after spawning, it is necessary to fish out and clean up the eggs in time.
