Volcanic stone (commonly known as pumice or porous basalt) is a functional and environmentally friendly material, which is a very precious porous stone formed by volcanic glass, minerals, and bubbles after a volcanic eruption. Volcanic stone contains dozens of minerals and trace elements such as sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt, and molybdenum. It is non radiative and has far-infrared magnetic waves. After a merciless volcanic eruption, after tens of thousands of years, Humans are increasingly discovering its value. It has now expanded its application fields to fields such as architecture, water conservancy, grinding, filter materials, barbecue charcoal, landscaping, soilless cultivation, and ornamental products, playing an irreplaceable role in various industries. effect

The role of volcanic rocks is 1: active water. Volcanic rocks can activate ions in water (mainly by increasing the content of oxygen ions) and can slightly release A-rays and infrared rays, which are beneficial for both fish and humans. The disinfection effect of volcanic rocks cannot be ignored, and adding them to an aquarium can effectively prevent and treat patients.

The role of volcanic rocks is to stabilize water quality.

This also includes two parts: the stability of pH, which can adjust water that is too acidic or too alkaline to automatically close to neutral. The stability of mineral content, volcanic rocks have dual characteristics of releasing mineral elements and absorbing impurities in water. When there is too little or too much, its release and adsorption occur. The stability of PH value of water quality at the beginning of Arhat and during coloring is crucial.

The function of volcanic rocks is to induce color.

Volcanic rocks are bright and natural in color. They have a significant color attraction effect on many ornamental fishes, such as Arhat, Red Horse, Parrot, Red Dragon, Sanhu Cichao, and so on. Especially, Arhat has the feature that its body is close to the color of surrounding objects. The red of volcanic rocks will induce Arhat’s color to become red gradually.

The role of volcanic rocks is 4: adsorption.
Volcanic rocks have the characteristics of porosity and large surface area, which can adsorb harmful bacteria in water and heavy metal ions such as chromium, arsenic, and even some residual chlorine in water that affect organisms. Placing volcanic rocks in the aquarium can adsorb residue that cannot be filtered out by the filter, as well as feces, to keep the water in the tank clean.

The function of volcanic rocks is to play with props.
Most of the fish, especially Arhat, are not mixed, they will also be lonely, and Arhat has the habit of playing with stones to build a home, so the lightweight volcanic stone has become a good prop for him to play.
The function of volcanic rocks is to promote metabolism.

The trace elements released by volcanic rocks can promote the metabolism of animal cells and carry out harmful halides in the body, cleaning up the dirt in cells
The role of volcanic rocks 7: optimizing growth.
Volcanic rocks can also improve the protein synthesis in animals, enhance the immune capacity, and to a certain extent, increase the mobility of Arhat. This also played a great role in Arhat’s beginning.

The Role of Volcanic Stone 8: Culture of Nitrobacteria.
The high surface area generated by the porosity of volcanic rocks is a good breeding ground for cultivating nitrifying bacteria in water, and their surface is positively charged, which is conducive to the fixed growth of microorganisms. They have strong hydrophilicity, and can greatly improve water quality by converting various causes of toxic NO2 and NH4 to relatively less toxic NO3.

The Role of Volcanic Stones 9: Matrix Materials for Water Grass Growth
Due to its porous nature, it is beneficial for aquatic plants to climb and root and fix their diameter. The various mineral components dissolved from the stone itself are not only beneficial for the growth of fish, but also provide fertilizer for aquatic plants. In agricultural production, volcanic rock is used as a substrate for soilless cultivation, fertilizer, and animal feed additive.

The Role of Volcanic Stones 10: Common Specifications and Particle Sizes for Aquatics
Filter material specifications and particle size: 5-8mm, 10-30mm, 30-60mm, commonly used in landscape design: 60-150mm, 150-300mm. Compared to other volcanic rocks in Yunnan, Tengchong and Shipai volcanic rocks are hard volcanic rocks mainly used for roads, bridges, buildings, and other purposes. Tengchong and Shipai volcanic rocks in Yunnan have the advantages of light weight, large quantity, and unique shape.
