CATDOLL : CATDOLL: How do I remove the oil film on the surface of the fish tank?

1. How to remove the oil film on the surface of the fish tank?

Use cotton cloth to gently wrap the oil film from underwater, lift it up gently, and filter it. This method basically removes it in one go. If you have time, you can also use a ladle to slowly skim it. Both methods are more environmentally friendly and will not damage the water quality.

2. How to deal with the oil film on the surface of the fish tank

1. Use an oil film processor to allow the oil film to enter the filter, use the filter cotton in the filter material to absorb it, and let the nitrifying bacteria decompose the grease.

2. Use a cup to slowly collect the oil film and discard it.

3. Use oil-absorbing paper to absorb the oil. You can place oil-absorbing paper at the diagonal of the water outlet (oil film gathering area) to absorb the oil film.

4. Install a trumpet mixer, suck the oil film into the mixer, pump it into water to mix with the water, and decompose it by adsorption through the filter cotton in the filter.

5. Clear the dirt in the filter.

6. Raising fish that feed on oil and fat (fish that float on the water surface and eat dirt on the water surface), such as black lady or black teapot, can reduce the formation of oil film.

7. The most recommended and only way to treat the symptoms and the root causes is to establish a stable biochemical system.

3. What should I do if there is an oil film on the fish tank?

Oil film usually appears in a grass tank, and there is rarely oil film in a bare tank. If you adjust the water outlet a little higher and let the water flow towards the water surface, no oil film will be produced.
