Volcanic stone can be put in the fish tank for a long time. Volcanic stone is the process of volcanic eruption after the cooling of magma when the letter is convex, there are a large number of dense pores inside, the quality is relatively light, put on the surface of the water can float up, so also known as pumice. This stone has many advantages, such as thermal insulation, acid, alkali and corrosion resistance, no pollution and radioactivity.
1. Regulate PH: The biggest advantage of volcanic stone for the fish tank is to regulate the PH of the water body. If the water is acidic or alkaline, it can be adjusted to be close to neutral, which is very good for fish farming, because both weakly acidic and weakly alkaline fish can accept neutral water quality.
2. Adsorption function: Volcanic stone can adsorb impurities in water, which can make the water more clear. It should be noted that it can also release minerals, so adsorption or release, mainly depends on the situation of the water body, minerals will be released when less, more will be adsorbed.
3. Enhance immunity: Volcanic stone itself contains certain minerals and trace elements, which are very helpful to the growth of fish. It can promote its metabolism, discharge harmful substances, and enhance the immunity of fish.
