Product overview
LCA Macro Mix (NPK) Liquid Fertiliser is made in Australia by Liverpool Creek Aquariums. It supplies nitrogen (N), phosphorus (P), and potassium (K), the three macronutrients plants use in large amounts.
If any of these run short, growth can stall and algae can take over. This concentrated mix is designed for split dosing, so you can add macros separately from traces and avoid the lock-up and oxidation that can happen when micro and macro nutrients sit together in one bottle.
