Ordinary tree roots are not suitable for landscaping in fish tanks. The main reason is not disinfection, but decay, which will affect the water quality. If it must be used, it must be deeply carbonized, and the process is as follows:

1. Peel this piece and wash it.

2. Natural drying until the moisture content of wood is lower than 10%.

3, into the wood drying room, so that the water content dropped below 3%.

4. Wood is pyrolyzed by high-temperature superheated steam above 200 degrees for a long time, so that nutrients are carbonized and water-absorbing groups are polymerized.

In fact, it is much more convenient to buy a ready-made heavy wood, and there is no need to spend a lot of money to make it yourself.
