If the black shell shrimp feces is not much, then there is no need to clean up manually. The feces will slowly sink to the bottom of the tank and then be decomposed naturally. But if the breeding density is high and there is a lot of feces in the black shell shrimp, then it needs to be cleaned up manually. Otherwise, the full tank is full of shrimp excrement flying, which not only affects the viewing, but also pollutes the water quality, affecting the normal growth of fish and shrimp.
To clean up the black shell shrimp feces, you need to use a filtration system. Install a filter system in the tank to help degrade shrimp droppings. When changing water, shrimp dung can also be cleaned manually. If there is a suction pipe, it can be directly used to pump shrimp dung out of the water. If the shrimp dung sinks to the bottom of the tank and is mixed with the bottom sand, a sand washer can be used to wash the sand and clean up the shrimp dung.
Changing the water is also a method to maintain the water quality. When changing the water, changing the shrimp dung and the old water together can also achieve the purpose of removing the shrimp dung. However, because the black shell shrimp is easy to die when the environment changes suddenly, it is better to change the water once a month. Every time you change the water, you can't change all the water, just change about one third or one half.
