Volcanic rocks can be placed in fish tanks for a long time. The formation of this kind of stone is related to volcanoes. There are many pores in it, and it is also relatively light. There are many advantages of raising fish with this stone, such as adjusting the pH of the water body and keeping the water neutral. At the same time, it also has adsorption function, which can absorb some impurities and keep the water clear. In addition, stones contain minerals, which can improve the immunity of fish. 1、 Can volcanic rocks be placed in fish tanks for a long time? Volcanic rocks can be placed in fish tanks for a long time. Volcanic stone is convex when Xincheng is cooled after the molten slurry during volcanic eruption. There are a large number of dense pores inside, and the quality is relatively light. It can float on the water surface, so it is also called pumice. This kind of stone has many advantages. It can keep warm and heat insulation. At the same time, it is also resistant to acid, alkali and corrosion. It has no pollution and radioactivity. 2、 What are the advantages of volcanic rock aquarium? 1. Adjust pH: the greatest advantage of volcanic rock for aquarium is to adjust the pH of water body. If the water body is acidic or alkaline, it can be adjusted to be close to neutral. Neutral water is very good for fish culture, because neutral water quality can be accepted whether fish like weak acid or weak alkaline.
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 whether it is adsorbed or released mainly depends on the situation of the water body. When there are few minerals, it will be released, and when there are more minerals, it will be adsorbed.
3. Improve immunity: volcanic rock itself contains certain minerals and trace elements. These things are still very helpful to the growth of fish. They can promote its metabolism, discharge harmful substances and enhance the immunity of fish. （HuoShanDanNengChangJiFangYuGangLiMa，HuoShanDanFangYuGangYouShenMeHaoChu）
