Terrdrakon substrate
Clay-based soil additive and depot fertiliser
Clay has very special and unique properties that predestine it as a substrate for plant aquariums.
It has similar properties to an ion exchanger and can therefore ensure an even supply of nutrients by absorbing them when there is an oversupply and releasing them again when required.
The black peat contains up to 35 % humic acids. It thus ensures the desired low pH in the soil environment, which, together with the property of humic acids to act as a weak chelator, ensures that the added nutrients remain in a form that is available to plants.
Together with the clay, this ensures that the nutrients are only released very slowly.
Our recommended quantity: approx. 1 g / 10 cm2 soil surface
| One pack of | is therefore sufficient for the following basic size |
| 250 g | 60 cm × 40 cm |
| 500 g | 100 cm × 50 cm |
| 1.000 g | 150 cm × 70 cm |
| 2.000 g | 250 cm × 80 cm |
Application
The substrate stains strongly, so wear gloves if necessary and take care not to contaminate clothing, carpets or furniture!
- Install underfloor heating (if available)
- Cover the underfloor heating with a third of the existing sand/gravel (make sure that no water stands on the surface)
- Terrdrakon evenly
- and cover with the remaining sand/gravel (at least 4 - 5 cm)
- Place a piece of plastic film or similar on top to protect it from being churned up
- Fill with 15 - 20 cm of water using a watering can and shower spout
- Remove the plastic film again before planting
- Plant the pool
- Fill in the remaining water

Terrdrakon substrate
Terrdrakon substrate has completely convinced me.
My plants (mainly Echinodorus) show extreme growth combined with strong colouring.
Terrdrakon doesn't have to shy away from comparison with significantly more expensive products, even after a year in my very densely planted high-light tank with CO₂ fertilisation, the plants show no signs of deficiency.
Only when using very fine sand should you add a layer of gravel to prevent the fish (catfish etc.) from stirring it up.
Conclusion: I can only recommend Terrdrakon substrate and will buy it again and again.
