LCA Phosphorus is a premium liquid fertilizer designed to deliver essential phosphorus (P) to aquarium plants. Phosphorus is a vital macronutrient that promotes strong root systems, vigorous growth, and enhanced coloration. This supplement is particularly beneficial in high-demand tanks with dense plant growth, CO₂ injection, or rapid nutrient uptake. Regular dosing helps prevent phosphorus deficiencies, which often cause slow growth and poor plant health.
