JBL - Manado - DARK activates the soil flora and is therefore an ideal substrate for plant care. JBL - Manado - DARK can be used as a sole substrate but also as a supplement, e.g. to JBL ProFlora AquaBasis. The substrate is excellently suited for burrowing fish, has a high iron buffer and, with its coarse surface structure, provides an excellent basis for colonisation by useful bacterial cultures as well as sufficient support for ground coverers. The nutrient buffer of the substrate can be recharged by surface fertilisation.
