For the new tank, water turbidity is a relatively common phenomenon. This is because the filter materials used are all new, and some granular impurities and short fibers will fall off. These things will cause turbidity when they enter the water. This kind of turbidity is commonly known as physical turbidity, the harm to the fish is relatively small, as long as through the strengthening of filtration, basically after a few days will be discharged these impurities, so that the fish tank becomes clear.
In addition to physical turbidity, there is also a kind of turbidity called biological turbidity. The organisms here refer to microorganisms, which multiply excessively, resulting in a foggy feeling in the water. Biological turbidity is extremely harmful, because these microorganisms will absorb organic matter, thus eliminating ammonia, which will increase the concentration of ammonia in water, resulting in the accumulation of toxins, leading to the death of fish. If we want to completely eliminate these microorganisms, we need to control them from the source. Since microorganisms feed on all kinds of organic matter, they should clean up the residual bait and fish feces in time, and strengthen filtration at the same time, which will make the water clear.
Fish farming generally requires the establishment of nitrification system, the core of which is nitrifying bacteria. This bacterium is different from the microorganism just mentioned, the microorganism mentioned above is heterotrophic bacteria, they will absorb organic matter and release ammonia, while nitrifying bacteria is just the opposite, it will absorb ammonia and convert it into nitrate, nitrate can be absorbed by plants in the water, thus completing the ecological cycle in the water. To set up a nitrification system, you need to add nitrifying bacteria, which are aerobic bacteria, so you need to turn off the light and explode oxygen after adding it, so that it can multiply rapidly.
