1. can the water goblin replace the filter?

The water goblin can replace the filter. It is a kind of filter itself. Its scientific name is sponge filter. The principle of this kind of filtration is to use the air pump to drive the water when the bubbles rise. Because the power and efficiency are not high, it is more suitable for small fish tanks and breeding tanks. If it is a large fish tank, it can also be installed as an auxiliary filter, but it still needs other filters. What are the benefits

of

filtration? 1. Maintaining water quality: The primary role of filtration is to maintain water quality. First of all, it can form water flow, once the water flows, it will reduce the growth of bacteria and reduce the rate of deterioration. At the same time, various filter materials can also filter out impurities in the water, so that the water body will become clean and sanitary, which is conducive to the health of fish.

2. Avoid algae explosion: Because filtration can form water flow, it can also cultivate nitrifying bacteria, thus reducing the content of ammonia nitrogen in water, thus avoiding the outbreak of algae. A small amount of algae in the fish tank can play a role in maintaining the ecological cycle, but too many will cause harm, which is very harmful to the fish.

3. Improve the dissolved oxygen: Usually, the filtration equipment does not contain an oxygen pump, but since it can make the water flow, it increases the contact between the water flow and the air, thus bringing part of the oxygen into the fish tank and improving the overall dissolved oxygen. However, for the fish tank with too high feeding density, the efficiency is not enough, and the oxygen pump is still needed.
