First explanation, usually mentioned that most fish friends of the yellow powder will be equal to the ivionic Woods. In most cases, it is right, but there are exceptions. Because the yellow powder drugs are other, such as Lifan Nuozo, there is a situation is that there is another kind of other drugs but it is yellow, because there is a percentage content, so it is not a fake medicine. If you have a sunlight in the sun, it is probably a furangnilu.

The main ingredient of domestic yellow powder is furan, which belongs to nitrofuran, and is the lowest price. Although it is low, the drug is good, but the toxicity of this drug is a big problem, it belongs to the largest ratio of nitrofuran drugs. The toxicity level reaches high toxic, so I saw a lot of fish friends, and the back is cold.

Relative to Japanese yellow powder, good effect, small toxicity, and use it according to his instructions, it is very good. Because of its main component is sodium furan sodium oxolate, the same belongs to nitrofuran, but toxicity is the second position of the series of drug retroats.

Powder product description, first of all, we must know what the yellow powder is, the main role, and the amount can be treated. It belongs to a conventional fish medicine. Everyone understands it.
