Sufficient for a 250L tank.

Plant Growth Substrate acts as a long term nutrition store for waterplants, so ensuring magnificent and healthy waterplant growth. Plant Growth 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 layer. Removing nutrition from water reduces the risk of undesirable algae growth.

Plant Growth Substrate is laid in a 1 cm thick layer on the bottom of the aquarium, when the aquarium is built. The table below provides recommended Plant Growth Substrate amounts for a number of standard aquarium sizes. 

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 Plant Growth 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.

I have a 4ft tank, looking to add a couple of cm depth to start with on the substrate and then place black sand on top. How many bags would i need to cover 2cm thick on a 4ft tank which is also 1.5ft wide? Thanks in advance


a 5L bag is good for 250L of water but that wouldn't be a 2cm depth so I'd opt for 2 bags in your situation.

can i use aquarium substrata in an establised tank?


you'd need to drain all the water first
