Experts talk about the precautions for raising hydroponic plants and fish

Hello, the precautions for growing hydroponic plants and fish are as follows:

There is an important benefit of growing hydroponic plants and fish: they are easier to grow in the water where the plants are cultivated. Insect eggs, if you release several small fish at the same time, the fish can eat the insect eggs, which is beneficial to maintaining a good indoor environment. At the same time, please note: You must ensure that the plants grown in hydroponics are non-toxic and will not cause harm to fish before you can safely grow fish and plants together.

Principle: Flower cultivation is the main purpose, and fish cultivation is a supplement. It is better to raise small fish.

First of all, do not feed fish. Fish food is usually organic matter, which will cause water quality to deteriorate and cause bacterial damage to plant root growth. In addition, healthy fish will not die if they are not fed for two to three months. On the contrary, overfeeding can easily lead to the death of ornamental fish.

Secondly, too much nutrient solution for hydroponic plants can also lead to fish death.

When changing the water, the temperature difference between the new water and the old water is too large. For example, the temperature of the water just taken from the tap water pipe in winter is very low. Changing the water directly will cause the fish to get sick and then die.

Tap water must be left for one or two days (or fish medicine Yulebao is added) before use, because chlorine (bleaching powder) in the water is not only bad for fish, but also for plant roots, and is harmful to fish. Just faster, it will lead to death.

The problem of hypoxia: Raising fish in still water can easily cause the fish to become hypoxic, and sometimes lead to death from hypoxia. As a reminder, plants also need oxygen in the water. Therefore, we should focus on raising flowers, supplemented by raising fish, and preferably small fish.

The water temperature should also be suitable for the species of fish being raised.

Fish have higher pH requirements for water than plants. If it takes a long time to change the water for plants, the pH of the water just changed will be different from the water before it was changed, because Excretions from plant metabolism are secreted from the roots into the water, causing small changes in the acidity and alkalinity of the water. Ways to reduce this change: Don’t change the water at intervals that are too long. In this way, it not only supplements oxygen for fish and plants, but also reduces the pH gap between the front and back water every time you change the water.

It will be better to put the fish in the bottle after adding the nutrient solution to the hydroponic plants.

Some fish that are delicate and unhealthy may die suddenly.
