PLANTS K: is a potassium fertiliser for all types of aquarium plants in freshwater aquariums. The aquarium potassium fertiliser supports the growth of the plants and prevents holey leaves due to potassium deficiency. ADVANTAGES: Our specially developed aquarium plant fertiliser contains potassium in a biologically available form and is very efficiently absorbed by aquarium plants. It is also free of nitrate and phosphate. CLEAN AQUARIUM: Unwanted growth of algae is not promoted by the potassium fertiliser, because a high density of aquarium plants naturally prevents the growth of algae. APPLICATION: The fertiliser should be used to specifically increase the potassium content. In doing so, 1ml of plant fertiliser per 100 litres of aquarium water increases the potassium content by 1.0mg/L. The optimal potassium content in freshwater aquariums is 5-10 mg/L. ARKA -: Is one of the world's leading brands in biological water treatment. The products are among the most environmentally friendly on the market - the application is safe and harmless.
