I bought a 60 cm wide aquarium with an oxygen pump and a filter pump, but the fish still went to the surface to get air. What's the matter? There are oxygen pumps in the water, fish are going to eat, those who play up the bubble is the ventilation, I do not understand these experienced friends teach me, I am a novice, and how to fish these thank you.
This is related to the density of the fish you keep in your aquarium, the type of fish you raise, and the quality of the water,Not oxygen pumps open is safe, fish tank small fish will also hypoxia, water quality is bad, such as new water did not raise good water, or water quality, excessive harmful substances, etc., will cause hypoxia,Again, there are still fish is the upper class fish, that is, like in the upper reaches of the activity, do not like to the middle or bottom swimming.
With these devices, the best, mainly water for too long, should be replaced at intervals of water, should be a long time, fish down things will damage water
You say the situation is similar to the fish floating head, is hypoxia phenomenon, but your aquarium is small, but the fish is not too much, the oxygen supply is more than sufficient, I think if it is not due to the hot weather caused it is hypoxia. You have to feed feed a little more than a few remaining, sulfur dioxide, ammonia nitrogen on the bottom of microbial decomposition produced, especially hydrogen sulfide are dissolved in water, is a great harm to the fish body. On the other hand, the excrement of fish remains in the pool, and the change of water is not in time, and the oxygen in the water will soon be consumed, and the fish will be poisoned. In this way, the efficiency of the filter pump should be strengthened, and the water will be changed slightly. The action of an oxygen pump is to make air into a vesicle, which increases the area of contact with water and more effectively dissolves oxygen in water.
I don't know what kind of fish you have. What's the size of it? In addition to some upper water fish, the water quality is also a key problem, if the local water is alkaline, the mineralization scale more devastating, with pure water and tap water up against the water, or by direct drinking machine out of the water line, and even see the water is very clear, but also a certain water quality well, because nitrogen in water containing ammonia gas is toxic, but can not see with the naked eye, it is best for a week for a two week cleaning water, a filter, the general fish will not die
