2. Magnetic treasure generally refers to magic magnetic treasure, which is a filter material product. Cibao has a particularly strong adsorption capacity. When it is placed in a fish tank, it can remove the odor, balance the PH value, and effectively solve the problems of turbid water, wrong water color and fishy water.

3. If it is a new fish, after 1 day in the tank, you can add magnetic treasure to the filter tank of the fish tank. After 6 hours, the water became clear and transparent, and there was no odor for a long time. If it is a used fish tank, you can directly add magnetic treasure to the filter tank, and the effect will be reflected in a few hours. If you use enough magnetic treasure, you can not change the water for half a year. You just need to wipe the fish tank wall and replace the filter cotton.

4. In addition, if the magnetic treasure is put into the tank for several hours, the water quality will become weak seriously, which may be because the toxic substances in the original water body exceed the standard or the dissolved oxygen in the water body is not enough.
