Potassium Sulfate K₂SO₄ – Dry Aquarium Fertilizer (1lb Bag)
Provides Potassium (K) & Sulfur (S) – Supports Leaf Development & Plant Resilience
Potassium Sulfate (K₂SO₄) is a high-purity dry aquarium fertilizer that supplies essential potassium and sulfur for aquatic plant growth. Potassium is a critical macronutrient that aids in photosynthesis, nutrient transport, and enzyme activation, especially under low-light conditions. Sulfur supports root development and protein synthesis.
K₂SO₄ is ideal for supplementing potassium in tanks already receiving nitrates (KNO₃) and phosphates (KH₂PO₄), helping prevent potassium deficiencies. Deficiency symptoms include leaf deformation, pinholes, and chlorosis. This highly soluble compound ensures fast uptake and optimal nutrient balance in demanding planted aquariums.
Includes:
Potassium Sulfate K₂SO₄ – 1 lb Bag
Guaranteed Analysis:
Soluble Potash (K₂O): 51%
(42% Potassium)
Sulfur (S): 18%
Derived From: Potassium Sulfate (CAS 7778-80-5)
