Elemental Potassium is a concentrated single-nutrient supplement for freshwater planted aquariums. It allows targeted potassium dosing without adding a complete fertilizer, giving you precise control over the nutrient level in the tank.

Potassium is an essential macronutrient used by aquatic plants for healthy growth and nutrient transport. A deficiency can appear as small pinholes, yellowing, or damaged areas in older leaves, sometimes progressing into larger holes as the leaf deteriorates. Elemental Potassium can be used to correct a potassium deficiency or as a supplement when your current fertilizer does not provide enough potassium for the needs of your plants.

It can also be used with other NilocG Elemental nutrients to create a customized fertilization routine tailored to your aquarium.
