Unfortunately aquarium plants don’t grow always as they are supposed to, even if nutrients and minerals are available. Research findings show that bacteria are responsible for the breakdown of the minerals and nutrients in the root zones. Certain bacterial mixed cultures can generate iron II accessible to plants out of worthless iron III. A targeted colonization of the aquarium substrate with these bacterial cultures can mean the plant’s root area is additionally protected against the intrusion of phytopathogenic fungi and blue-algae (cyanobacteria) growth is also hampered by the biofilm. The aquarium owner can see the effectiveness of JBL ProScape PlantStart by quick and vigorous plant growth and a substrate free from cyanobacteria or fungal infestation.
