LCA NP Free 250ml Liquid Fertiliser – Potassium & Trace Elements for Planted Aquariums

LCA NP Free is a specialised liquid fertiliser designed to provide Potassium (K) and essential micronutrients without adding extra nitrates or phosphates. Perfect for high-bio-load aquariums or shrimp tanks, this fertiliser ensures plants receive the nutrients they need while maintaining water quality.

It also boosts carbon levels, helping to inhibit algae growth and enhance plant growth. When nitrate and phosphate levels are already adequate, LCA NP Free delivers a complete micronutrient profile to support even the most demanding planted tanks.
