Hydrogen Peroxide in Aquaponics
On the Application of Hydrogen Peroxide in Aquaponics
Aquaponics is an ecosystem that combines aquaculture with hydroponics. In this system, fish excrement provides nutrients for plants, and plants purify water bodies for fish to survive. The two complement each other. However, to maintain the stability and health of this system, various means are often required, and hydrogen peroxide plays an important role in it.
Hydrogen peroxide, with a chemical formula of $H_2O_2 $, can be used as a water quality improver in aquaponics systems. After it dissolves in water, it can decompose to produce oxygen and water. Oxygen is essential for aquaponics, and fish survival and microbial decomposition of organic matter require sufficient oxygen. When the amount of dissolved oxygen in the water body is insufficient, an appropriate amount of hydrogen peroxide can quickly increase the dissolved oxygen in the water, ensuring the normal respiration of fish and the activity of microorganisms in the system.
In addition, hydrogen peroxide has strong oxidation, which can effectively kill some harmful bacteria, viruses and parasites in the water body. In the fish-vegetable symbiosis system, if the water quality is poor, it is easy to breed various harmful microorganisms, threatening the health of fish and plants. Timely use of hydrogen peroxide can inhibit the reproduction of harmful microorganisms, reduce the probability of fish diseases, and create a healthy growth environment for plants.
When using hydrogen peroxide, caution is also required. First, concentration control is extremely critical. If the concentration is too high, although the bactericidal effect is significant, it may cause harm to fish and plants. The strong oxidation of high concentrations of hydrogen peroxide may damage the gill tissue and body surface mucosa of fish, affecting the normal physiological function of fish; for plant roots, it may also inhibit their growth and even lead to root necrosis. Second, the frequency of addition should be reasonably planned. Frequent addition of hydrogen peroxide may cause imbalance of microbial community in the system. Beneficial microorganisms in the system are of great significance for maintaining water quality stability and decomposing organic matter. Excessive use of fungicides may destroy this balance and affect the self-purification ability of the system.
To make hydrogen peroxide work best in the aquaponics system, users need to fully understand the system water quality status, fish and plant growth stages and other factors. Regularly test the water quality, and accurately determine the dosage and frequency of hydrogen peroxide use based on dissolved oxygen, microbial indicators and other data. Only in this way can we ensure the health of the water quality of the system, avoid unnecessary damage to fish and plants, and achieve efficient and stable operation of the fish-vegetable symbiosis system.
