The functions of placing sunken wood in fish tanks:

1. Adjust PH. It can slowly adjust the pH to make the water acidic, which is beneficial to the growth of many fish that like acidic environments.

2. Increase beauty. There are many shapes of deadwood, and when combined with aquatic plants, you can create a very beautiful waterscape in the fish tank.

3. Provide shelter. Many fish and shrimp are very timid and easily frightened, and the fallen wood itself has many branches, which just provides a convenient place for fish and shrimp to hide.

Steps before placing the sunken wood into the tank:

1. Clean the dirt. Use clean water to scrub the deadwood clean, especially the branch branches where dirt or bacteria may be hiding, so scrub carefully.

2. Boil in water to disinfect. After washing off the dirt on the surface of the sunken wood, boil the water and put the sunken wood in and boil it for ten minutes to fully disinfect and sterilize the bacteria on the wood.

3. Sun exposure. After boiling the sunken wood, expose it to the sun until the inside and outside of the sunken wood are completely dry and there is no moisture, then you can put it in the fish tank for scenery.
