Drip box is generally divided into three layers.The first layer should be covered with a glass ring and covered with a layer of biochemical cotton, which can filter larger dirt, so that it can fall to the bottom, and also allow the next level of filter material to fully contact the water flow.The second layer is laid with biochemical cotton below and suction filter cotton above, which can filter some fine particles.The third layer is covered with a wool pad, on which some special filtering materials can be placed.
1, not beautiful: because the drip box is external, the whole and the fish tank does not match, put on the outside looks a little not beautiful.Some filtration equipment, such as bottom filtration, side filtration and so on, are all in the fish tank, and the fish tank is integrated, so it will not feel particularly abrupt.
2. Occupying space: The drip box occupies more space. There is no way to solve this problem, because its own filtering function is relatively strong. At the same time, it needs a lot of filter materials. If you remove a few, although the occupied space is small, the effect is not as good as before. For the health of the fish, you still need to leave a few more layers.
3. Temperature difference: The drip box is external, so the water will come out. In this way, it is not good to keep warm. It is a trouble for keeping tropical fish.To solve this problem, we can only add a lid on it and then put a heating rod on it, so that we can control the water temperature well.
