In order to promote the work of micro organisms , it is suggested to sprinkle the following under the soil:
1. Bacter 100
It contains more than 100 kinds of substrate bacteria in a dormant state. By sprinkling on the base substrate, it can make an ideal substrate environment. Another great feature of Bacter 100 is that it can suppress the growth of green algae by applying a bit of it on the effected portion.
2. Clear Super
It is a substrate additive made from activated carbon and organic acid. Clear Super helps the growth of micro organisms. By sprinkling on the base substrate, it promotes the growth of micro organisms in the substrate and stabilizes the environment.
3. Tourmaline BC
This contains fine bamboo charcoal, giving it the ability to absorb organic pollutant substances. Add some over the substrate during the initial set-up and it will help to improve the substrate environment.
4. Penac W
It prevents the substrate from becoming anaerobic and improves the substrate environment.
It is also available in small packets which can be used for tanks upto 60cms in length
