GLA Magnesium Sulfate (MgSO4) Aquarium Fertilizer - 1lb Jar

Magnesium Sulfate MgSO₄ – Aquarium Plant Nutrients (1lb Jar)

Provides Magnesium (Mg) & Sulfur (S) – Essential for Chlorophyll, Enzyme Function & GH Balance

Magnesium Sulfate (MgSO₄) is a critical source of magnesium and sulfur—two essential macronutrients that support healthy aquatic plant growth. Magnesium is the central atom in chlorophyll and plays a vital role in phosphorus uptake, iron utilization, and enzymatic activity. Sulfur is essential for root development and protein synthesis.

This formula helps raise general hardness (GH) in soft or RO water and prevents magnesium deficiencies that lead to yellowing leaves, interveinal chlorosis, and poor root structure. Ideal for balanced mineral supplementation in planted aquariums.
