Specialized Fertilizer is added each week when the water is changed. The pump bottle dispenses 1,2 mL per push.
We recommend 6 mL (5 pumps) per 50 L water weekly. However, we recommended that this is set in accordance with plant requirements. Specialized Fertilizer contains, in addition to micro-nutrients, all essential macro-nutrients. The fertilizer is particularly suitable where plants display a lack of nutrition. However note that if algae growth starts, Specialized Fertilizer will promote this growth.
Specialized Fertilizer contains nitrogen (N) and phosphorus (P). Dosage must therefore be adapted to plant absorption rates, to avoid undesirable algae growth. Where signs of algae growth develop, reduce the dosage by 50% and increase water changing frequency by 50%. Changing the water not only reduces the concentration of nutrients in the water, but also removes algae spores, remnants and other accumulated elements from the aquarium water.
