JBL ProScape Plant Start is a ground activator for quick plant start in the aquarium. When plants are initially inserted it takes quite a while until they have formed roots strong enough to anchor them well at the bottom. With JBL PlantStart you reduce this firm rooting time and the plant growth starts almost immediately. The special bacterial mixture (mixed culture) makes the intake of nutrients and trace elements easier for the plants. The precipitated iron III is transformed into iron II which is accessible to the plants.Another benefit of JBL PlantStart emerged in tests: the bacteria form an initial colonisation on the substrate fairly quickly and break down organic material. This way even a newly added substrate becomes a functioning additional filter in an extremely short time. Using the biofilm formed JBL ProScape PlantStart reduces the colonisation of blue-green algae (cyanobacteria).Contents: 2 individually sealed metallized bags, each with 8 g mineral granulate with live bact
