Seachem Aquarium accessories Flourish Phosphorus

Phosphorus supplement for planted aquariums. Phosphorus is one of the three vital elements needed by plants. Flourish Phosphorus is a safe potassium phosphate supplement (4500 mg/L), simplifying phosphate dosing. Nitrate-free, it allows dosing according to plant needs, without the risk of overdosing. Flourish Phosphorus will improve and accelerate plant growth without promoting the appearance of algae. As planted aquariums often lend themselves to the maintenance of shrimps and snails, Flourish Nitrogen is harmless to invertebrates.
