Nitrogen (N) is one of the main three macro nutrients (nitrogen, phosphorus, potassium: NPK) required by plants and when deficient, becomes the limiting factor for healthy plant growth. Central to plant growth, this macro-nutrient is one of the most basic and critical building blocks of plant proteinFull 3x per week dosing with LCA Nitrogen will meet the needs of even the most demanding tankINSTRUCTION: Dosage rate for 100L TankSHAKE WELL BEFORE USEUse 1 pump (2ml) per 100L, 3x per week with 50% weekly water change. • For HIGH LIGHT tanks with injected CO2, dense plant mass and good flow - instead use 3 pumps per 100L, 3x per week (maximum dosage) with 50% weekly water change.• For LOW LIGHT tanks, dose the normal amount but only 1-2 times per week.'*Amounts above are for reference only. Your planted aquarium may need more or less depending on many factorsWARNING: 3 PUMPS PER 100L IS THE MAXIMUM DOSAGE. DO NOT OVERDOSE Analysis3 pumps in 100L yieldsNitrogen ( N ) 1.69ppmNitrate ( NO3) 7.50ppmPotassium ( K ) 2.3ppmCalcium (Ca) 1.21ppmTarget ranges in parts per million (ppm) for High Light Planted.Nitrate (NO3) range 20-30 ppmPotassium (K) range 15-30 ppmPhosphate (PO4) range 2-6 ppmIron (Fe) range 0.5-1.5ppm (or higher in some cases)**It's important to note that these are equivalent weekly doses. For example, to achieve 20-30ppm nitrate you would dose All-in-One Fertiliser 3-4x per week.**KEEP OUT OF REACH OF CHILDREN
