from the fish tank? If you want to remove the oil film on the surface of the fish tank, you can strengthen the filtration. If the filtration effect is good, the oil film can be sucked into the filter tank. If the filter is not qualified, it needs to be cleaned manually. You can find a small cup and slowly scoop out the oil on the surface. In addition, it can also be absorbed with oil absorbent paper. Some fish also have the characteristic of swallowing oil film, such as guppy, teapot fish and so on, they can eat the oil film.
oil film come into being? 1. The feed is not good: The reason why the oil film appears is most likely the problem of the feed. The oil content of the fish food is too high. In this case, what needs to be done is to change the feed and choose some less oily food for feeding. In addition, each feeding can not feed more, to ensure that the fish in 5-10 minutes to eat.
2. Aging of filter material: If the filter material has been aged, grease will also overflow, resulting in oil film on the water surface. Generally, filtration equipment has a service life, which needs to be cleaned after a period of time, and if it can not be washed out, it has to be replaced. However, it should not be cleaned frequently, so as not to destroy the ecological balance in the tank.
3. Impurities in water: As the water used for fish farming is tap water, there will inevitably be some impurities in the water, which will also form an oil film. Generally, the water used to change the fish tank must be used to ensure the precipitation of impurities, while maintaining filtration, which can also remove the oil film.
