LCA NP Free 500ml Liquid Fertiliser – Potassium & Trace Elements for Planted Aquariums

LCA NP Free is a specialised liquid fertiliser designed to supply Potassium (K) and essential micronutrients while excluding extra nitrates and phosphates. Perfect for high-bio-load aquariums or shrimp tanks, it ensures plants receive vital nutrients without affecting water quality.

It also boosts carbon levels, helping to inhibit algae growth and enhance plant growth. When nitrate and phosphate levels are sufficient, full 4x per week dosing ensures your plants thrive, even in demanding setups.
