The water and fertilizer in the fish tank have little nutrition for the fish itself.However, water and fertilizer may promote the reproduction of microorganisms, but also increase the risk of algae explosion, and after a large number of microorganisms multiply, organic matter in the water will be decomposed into ammonia nitrogen, which will cause some harm to fish.On the other hand, algae explosion can also lead to the reduction of dissolved oxygen in the water body, which is not conducive to the breathing of fish.
1. Suspend feeding: The reason why the water in the fish tank becomes fat is mainly due to too much feeding. Whether it is some feces after being eaten by the fish or the residual bait that falls to the bottom of the water before being eaten, they will be decomposed by microorganisms, thus making the water body fat. Therefore, if you want to solve this problem, It is necessary to suspend feeding for a period of time, and then reduce the amount of feeding.
2. Raising tool fish: Since the water is too fat because there are residual baits in the water, as long as you raise some tool fish that can eat the residual baits, you can also temporarily alleviate this problem. The most commonly used tool fish is the scavenger. It is a benthic fish itself, and its mouth is below, which is convenient for it to suck the residual bait at the bottom of the water.However, this method can not really change the phenomenon of over-fertilization of water, because it will also have excrement after eating, so it still needs to change water filtration.
3. Water change and filtration: The water must be changed for fish farming. The cycle of water change is usually one week. When the water is changed each time, the water at the bottom can be pumped out with a pipe. In this way, the dirt at the bottom of the water can be sucked away.In addition, if there are filters, they can also be filtered out.
