Tropica Plant Substrate acts as a long term nutrition store for waterplants, so ensuring magnificent and healthy waterplant growth. Tropica Plant Substrate is a natural concentrate of clay and sphagnum, laid at the bottom of the gravel layer when you build your aquarium. Clay and sphagnum slowly release nutrients to waterplant roots and binds nutrition in the water in the bottom layerund. Removing nutrition from water reduces the risk of esirable algae growth.

Use of Tropica Plant Substrate:
The substrate is laid in a 1 cm thick layer on the bottom of the aquarium, when the aquarium is built. A layer of gravel of minimum 3-4 cm thick is then laid over the substrate. The gravel acts as a barrier between the concentrated Tropica Plnat Substrate and the water. Plants are planted in the gravel in the normal way and new roots quickly form in the substrate. When planting, disturb the substrate as little as possible, to avoid clay and sphagnum particles being mixed into the water. If plants are to be removed from the aquarium, cut the plants at the plant/root transition to avoid the plant substrate mixing with the water. Plant roots are left in the bottom layer. They are quickly broken down, so providing nutrition to other plants in the aquarium.
