Aquarium Co-Op Easy Potassium Liquid Fertilizer

Aquarium Co-Op Easy Potassium is a concentrated liquid aquarium fertilizer designed to supply essential potassium to freshwater aquarium plants. Potassium is one of the primary macronutrients required for healthy plant growth and is especially important for stem plants, root-feeding plants, and fast-growing planted aquariums.

When potassium levels become depleted, aquatic plants may develop pinholes in leaves, yellowing, weak growth, or deteriorating foliage. Easy Potassium helps correct these deficiencies, supporting stronger growth, healthier leaves, and improved plant coloration.

Suitable for both low-tech and high-tech planted aquariums, Easy Potassium is safe for fish, shrimp, snails, and other freshwater livestock when used as directed.
