Seachem Flourish Phosphorus 250ml Phosphate solution
Flourish Phosphorus is a safe solution (4500 mg of phosphate per litre) of potassium phosphate, allowing precise dosing of this substance. Unlike other similar products, which contain a mixture of nitrates and phosphates, Flourish Phosphorus allows phosphorus to be supplied in the optimum amount for plants without the risk of raising nitrate levels. When used as directed, it accelerates the growth of aquatic plants.
It is recommended to use it together with Flourish Nitrogen and Flourish Potassium. Flourish Phosphorus does not contain nitrogen, allowing phosphorus levels to be increased without the risk of increasing nitrates.
Directions for use:
Beginners: 2.5 ml (half a cap) for every 80 litres of tank capacity, once or twice a week as needed. Phosphorus deficiency manifests itself, among other things, in stunted growth and dark green colouring of the shoots.
Advanced: The dose recommended for beginner aquarists increases the phosphorus level by 0.05 mg/l (0.15 mg/l for phosphates).
The optimum level of this element may vary depending on the planting of the aquarium, but is usually between 0.15 and 1.0 mg/l. It is recommended to check the phosphate level with a suitable test. The following formula may be helpful in obtaining the correct phosphorus level: 0.2vp=m, where v= volume of tank in litres, p= planned increase in phosphorus level, m= volume of Flourish Phosphorus preparation. For example, if we want to increase the phosphorus level to 0.1mg/l in a tank of 80 litres, we need to add 0.2x80x0.1=1.6 ml of preparation.
