With TetraPlant Amin my aquarium plants are literally skyrocketed. Although I also use ground substrate I always notice when I PlantaMin should admit after water changes, that the plant after getting the day a huge growth spurt. In my second aquarium I only use PlantaMin liquid fertilizer without additional fertilizer. And even there the plants grow well. Can find no less than as the sole fertilizer in the aquarium use. Price-performance is top. Total: Unrestricted to Share. Therefore 5 stars
