between fish excrement and fish eggs is easy to distinguish between fish excrement and fish eggs. The former is strip-shaped and easily broken, and has no luster itself, while the latter is grain-shaped, looks shiny, and with the passage of time, black spots will appear on it. However, it should be noted that only fertilized eggs will have these changes, unfertilized eggs will not have black spots, will always be white, and will rot in water.
1, change water to clean up: fish excrement too much, the most direct way is to change water to clean up. Find a pipe, one end to the bottom of the tank, the other end on the outside, the position should be lower than the fish tank, so that the water can be pumped out. When pumping water, the fish excrement at the bottom of the tank will also be sucked out, thus improving the water quality.
2. Strengthen filtration: If the filtration effect of the fish tank is not good, the fish excrement will gradually accumulate. If you want to strengthen the filtration, you can change a more powerful filter, or clean the filter equipment, especially the filter cotton and other easily blocked filter materials, which can also make its effect better after cleaning.
3, reduce feeding: The reason why fish excrement is more, because usually feed too much, fish eat more, naturally pull more. So if you want to control the amount of fish excrement in the tank, you can reduce the feeding. However, it can not be fed for a long time, otherwise the fish will become an old fish because of malnutrition, seriously affecting the ornamental.
