Promote healthy, balanced aquatic plant growth with Seachem Flourish Phosphorus, a concentrated phosphorus supplement designed for freshwater planted aquariums. Phosphorus is an essential macronutrient involved in energy transfer, photosynthesis and cell development, helping aquatic plants grow and thrive.
Flourish Phosphorus provides a controlled source of phosphorus to replenish nutrients that may become depleted in planted aquariums, particularly in densely planted aquascapes where plant uptake is high.
Essential plant macronutrient: Supplies phosphorus required for healthy aquatic plant development.
Supports plant growth: Helps support energy transfer, root development and new growth when phosphorus is limiting.
Helps prevent phosphorus deficiency: Useful for plants showing signs of slow growth or poor development associated with insufficient phosphorus.
Ideal for planted aquariums: Suitable for aquascapes with moderate to high plant nutrient demands.
Controlled nutrient supplementation: Allows aquarists to adjust phosphorus levels according to plant requirements.
Complements other fertilisers: Can be used alongside Seachem Flourish Nitrogen, Potassium and comprehensive plant supplements.
Suitable for aquascaping: Helps maintain balanced nutrient availability in carefully maintained planted tanks.
Standard dosage: Add 2.5mL per 80L of aquarium water to increase phosphate by approximately 0.05mg/L.
Dose according to plant growth, existing phosphate levels and aquarium conditions.
For smaller aquariums, measure carefully using an appropriate dosing syringe.
Monitor phosphate levels and adjust dosing as required.
Avoid excessive nutrient accumulation, particularly in aquariums prone to unwanted algae growth.
