As the size of the aquarium increases, the number and size of the plants also increases. For this reason, we have developed our Plant System, a system with highly concentrated components. The components Plant System V30 (complete fertilizer), Plant System S7 (vital substances) and Plant System E15 (iron fertilizer) are therefore designed to meet the needs of large aquariums. All macro and micro nutrients and trace elements are covered. Plant System V30 specifically compensates for nutrient deficiencies, strengthens the plants from the inside out and helps with stagnant growth. Highly effective protective covers – so-called chelates – keep the nutrients available to the plants for a long time. Deficiency symptoms are permanently eliminated and the plants appear in a magnificent green again. Guaranteed to be phosphate and nitrate free – does not promote algae.
