JBL ProScape Volcano Powder 250g

JBL ProScape VolcanoPowder is NOT a JBL Volcano Mineral, but it is a mixture of basalt rocks without nitrogen (N) for long-term soil fertilization. JBL ProScape VolcanoPowder must be poured directly onto the bottom of the aquarium before the soil falls asleep. In this case, the plants will receive valuable minerals for several months or even years for healthy growth.
