NatureHolic – Potassium Booster Fertilizer

The liquid NatureHolic Potassium Booster with immediate effect is a potassium-containing aquarium fertilizer for aquascaping and for all planted aquariums. The important macronutrient potassium (K) is needed by aquarium plants to regulate their water balance and thus the nutrient transport in the plants.

A deficiency of potassium manifests itself in black dot-shaped necroses in the leaf tissue, which later become holes. A potassium deficiency is particularly noticeable in java ferns. Here, entire leaf parts first turn yellow, then black, and then the leaf falls off. If the plant does not have sufficient potassium available, it usually also grows poorly and generally does not appear vital.

Nutrient gaps in the aquarium are readily exploited by algae. If the aquatic plants in the aquarium can no longer grow properly due to a lack of the important macronutrient potassium, an algae plague can result.

With the NatureHolic Potassium Booster potassium fertilizer for the aquarium, the plants grow well again, the new leaves no longer have yellow or black spots, the leaf tissue looks stronger. The nutrients in our NatureHolic Aquascaping fertilizers are in a form that is absolutely harmless for fish and invertebrates in the aquarium when dosed correctly. Even for sensitive shrimp, our NatureHolic Potassium Booster Aquascaping Fertilizer is definitely harmless. Its stabilization in NatureHolic Potassium Booster makes it easy for aquarium plants to absorb the important plant nutrient potassium through their leaves.

For reasons of sustainability and environmental protection, we do not use unnecessary fragrances and dyes in our NatureHolic aquarium fertilizers. The high quality and high yield NatureHolic Aquascaping fertilizers are characterized by their high efficiency.

Dosage: NatureHolic Potassium Booster is added either daily or as a shock fertilization once a week after the water change. Then the daily fertilization is extrapolated accordingly to seven days.

Aquariums with strong light and with CO2 fertilization receive 2 ml of Potassium Booster per 100 liters per day, without CO2 supply 0.5 ml. Aquariums with medium strong light with CO2 fertilization receive 1 ml, without CO2 supply 0.25 ml. Low light aquariums do well with CO2 fertilization with 0.5 ml, without CO2 supply with 0.1 ml Potassium Booster.

These dosage recommendations are guidelines; if necessary, please adjust upwards or downwards  individually to the aquarium! If the potassium value in the aquarium increases too much, the fertilizer quantity is reduced accordingly. A target value of approx. 10-15 mg potassium per liter aquarium water should be aimed at. A good water test for aquariums helps to monitor the potassium value in the aquarium. We recommend a weekly water change of about 25-70% to prevent nutrient peaks from forming in the aquascape, which can promote algae.

We recommend the use together with the other Macronutrient fertilizers products from NatureHolic and the Complete iron fertilizer so that the plants in the aquascape or planted aquarium are supplied with everything they need.
