Product overview
LCA Phosphorus (P) Liquid Fertiliser is made in Australia by Liverpool Creek Aquariums. Phosphorus is one of the three core macronutrients (the P in NPK) and is used in plant energy transfer, including ATP, which supports photosynthesis and tissue repair.
Fish waste adds some organic phosphate, but high-tech tanks with strong lighting and injected CO2 often use it faster than the bio-load can replace it. This single-nutrient formula lets you raise phosphate without adding extra nitrates.
Key features
-
Targeted macronutrient: Concentrated phosphorus for dense, fast-growing stem plants.
-
Helps treat deficiencies: Used to correct lower leaf drop, unusually dark green or purple tinting, and stalled root growth.
-
Supports plant energy: Supplies phosphate for ATP production, nutrient use, and overall plant health.
-
Independent dosing: No added nitrates, so you can control phosphate as part of an Estimative Index (EI) or custom routine.
-
Pump dispenser: Easy, mess-free dosing with no syringes or measuring cups.
Water and system compatibility
-
Water: Freshwater aquariums only. Not for marine or reef tanks.
