The Perfect Plant fertilization system
The DENNERLE fertilization system consists of a basic fertilization and a supplementary fertilization stage. The basic fertilizers E15 FerActiv iron fertilizer and V30 Complete special fertilizer introduce into the aquarium those nutrients which can remain present for extended periods. The supplementary fertilization, using S7 VitaMix, provides those nutrients which are consumed rapidly and of which a long-term supply cannot be built up. S7 VitaMix is therefore added on a weekly basis.
