Usage calculation reference
Artificial soil usage(L)=Tank Length (cm) x Wide (cm) x Soil Height 5(cm)/1000.

Example: Tank size 30cm Length x 20cm Wide, Using artificial soil:30 x 20 x 5/1000=3L=1bag.

Usage
1. Spread 4 to 5 cm height of our artifcial soil at the bottom of the tank. The layer at the front of tank should be lower than the back.
2. Put a flat plate on the soil and pull the water through the plate slowly. In this way it can decrease the force from water to prevent the water getting turbid.
3. Keep the filler working for at least 12 hours and then you can put your fishes into the tank.
