Natural substrate which filters and enhances plant growth.
- Supports the filter with its large colonisation area for pollutant-absorbing bacteria.
- The special structure supports the development of plant roots.
- Restricts the growth of algae by absorbing excess fertiliser.
- The rounded shape is also gentle on the sensitive barbels of ground-dwelling fish.

Can JBL Manado be used with a substrate heating cable additionally, or would that lead to overheating?
I don't see a risk of overheating as long as the substrate heating cable is installed properly with the spacers and is not placed directly on the glass pane.
While adding JBL Manado to the tank, we noticed a magnetic component. What is that?
Manado is produced from a natural raw material (clay), which can exhibit slight fluctuations in mineral composition, depending on where it was found. The "magnetic component", which can be traced to iron kernels, occurs in isolated cases, but does not have any harmful effect on tank operation. Quite the contrary, plants need iron as a trace element and use it.
Why does foam form on the water surface after I add JBL Manado?
Even if remote diagnoses are extremely difficult here, the formation of foam on the water surface is an indication of too many organic components, particularly protein, which foams as a result of the water agitation. This would have to be confirmed by taking samples, though. As JBL manado is free of organic substances, one can be quite sure that it is not the cause of the foam.
Can I use a gravel cleaner with JBL Manado?
Manado has a lower specific weight than gravel. The substrate can usually be cleaned with a gravel cleaner of sufficient width.
If Manado is suctioned with too much force, it helps to decrease the suction power by means of a stopcock, for example.
If a tank has just been set up, normally, the bottom does not need to be cleaned thoroughly, and cleaning can be limited to the upper part of the tank.
