Should I add salt to the fish tank? What is the effect of adding salt to the fish tank? These two questions have been considered by many aquarists. Many breeders believe that adding salt to the fish tank can better sterilize and disinfect, which is good for aquarium creatures. However, in fact, whether it is necessary to add salt to the fish tank, and what effect this has on the fish needs a comprehensive analysis.

The study found that human saline is 0.9%, that is, 0.9 grams of salt is prepared, and water can be added to 100 ml; Fish are different, so the normal saline concentration of fish is by no means 0.9%. And different fish have different requirements for water quality and environment. For example, freshwater and marine fish have different requirements for the water environment. Therefore, adding salt to the fish tank also needs to be determined according to the specific aquarium species being raised.

However, objectively speaking, adding salt to the fish tank also has some effects, such as the following:

1. It can be disinfected and sterilized, and different proportions can treat and prevent different The main purpose is to disinfect the bacteria, trichocarpus, and tubeworms on the surface of the fish.

2. It can be used as an adjuvant drug treatment to treat some diseases of the fish, such as saprolegnia and so on. Because salt can promote the absorption of drugs by fish skin, so that it can enhance the efficacy of drugs.

3. It can balance the osmotic pressure. We all know that the salt content inside and outside the fish is different, and there is a certain osmotic pressure. Therefore, by adding salt, part of the salt lost due to the wound can be replenished, or Because the fish is only in a new place, it can relieve the discomfort of the water quality, that is, adjust the osmotic pressure.

4. It can purify the water body. The mechanism of action of salt is to increase the ion concentration in the water, so that the suspended organic particles and colloids form flocs and settle to the bottom of the pool, which not only reduces the consumption of dissolved oxygen, but also reduces the consumption of dissolved oxygen. Purified water bodies.

Finally, it can better stimulate the appetite of fish, because in the physiological process of fish, NaCL as an inorganic salt is necessary to maintain life. Na+ is essential for maintaining body osmotic pressure, water balance and acid-base balance. Na+ can also maintain and improve neuromuscular excitability. CL- is a component of hydrochloric acid in gastric juice. The function of hydrochloric acid is that it can activate pepsinogen, supply the acidic environment required by pepsin, denature the protein in food, and help digestion.
