Special aquaria need special care:
The DENNERLE Daily Fertilizers, Fertilizer Tabs and growth promoters
For normal aquaria containing a balanced stock of fish and plants, the classic DENNERLE fertilization system, including E15 FerActiv, V30 Complete and S7 VitaMix, does the job perfectly. But for special aquaria, DENNERLE offers the following supplementary fertilizers, each one carefully formulated to meet the respective requirements. The daily fertilizers are used instead of S7 VitaMix.
