Recently, I received a question from an aquarist in my private message: Can yellow powder be dropped when the fish has no disease? In today's article, we will answer this question. First of all, let's understand the role of yellow powder. The main role of yellow powder is sterilization, inhibition of bacterial growth, for the control of ornamental fish rotten fins and other bacterial pathologies have a good inhibition, control effect and therapeutic effect.

Ornamental fish do not need to be drugged when they are not sick. The aquarist who wants to drug when the ornamental fish is not sick may be hoping that yellow powder can play a preventive and bactericidal role. Let's start with the prevention aspect.

I don't think it's necessary to put down yellow powder to prevent ornamental fish diseases. Yellow powder is generally used directly as a treatment, if one of the ornamental fish in the same tank has a disease that can be treated with yellow powder, it can play a preventive and therapeutic effect under the whole tank of yellow powder. If your fish is just in the tank, that is, a newly bought ornamental fish, then you can also put some yellow powder for quarantine to kill the bacteria carried by the ornamental fish. However, the main role of yellow powder is sterilization, ornamental fish used for quarantine need to be drugged in the whole tank, if the yellow powder is more for nitrifying bacteria, the amount of yellow powder under quarantine does not need too much.
So is it feasible to sterilize yellow powder? Yes, yellow powder can also be used as a newly opened sterilization drug. However, the yellow powder used for sterilization can often only be used in the early stage of opening the cylinder, and the water needs to be slowly changed in the later stage, the yellow powder component is replaced, and then the nitrifying bacteria and other probiotics begin to multiply. The nitrifying bacterial system established to the later stage often does not need to be sterilized under yellow powder, the fish are very healthy, the bacteria are fine, they have established a stable ecosystem, and the yellow powder will destroy the bacterial system and make the ecological balance unbalanced.

Ornamental fish with some bacterial diseases can rely on yellow powder to treat them. If the infection of that disease is more severe and serious, then it is necessary to quickly put the whole tank together under the yellow powder for treatment. The medicinal effect of yellow powder is relatively mild, suitable for long-term medicinal baths, and there are signs of improvement in the later stage to start changing the water. If the reason for the disease of ornamental fish is because of their own poor physique, then fish out for treatment alone, other ornamental fish with strong physique often do not have the same pathology without special reasons.
In general, as long as ornamental fish are sick, and yellow powder belongs to the special medicine of that disease, then there is no doubt that yellow powder can definitely be placed. But if the ornamental fish is not sick, the individual physique is strong, the water quality is also very good, there is no odor discoloration, then the yellow powder does not need to be down, this needs to be determined by the situation.
We have often mentioned in our usual articles that "it is a three-point poison of medicine", in order to remind everyone that there is nothing to do without drugging, indiscriminate drugging can not treat ornamental fish diseases and prevent pathologies, but will be counterproductive and destroy the ecosystem. Creating an imbalance in the ecological balance.
Drugs are not omnipotent, as long as they can be slowly conditioned, such as congestion or something can be cured by conditioning, the next large number of drugs will stimulate fish.
