Seachem Flourish Phosphorus, 250 ml

Flourish Phosphorus™ is a safe way to add potassium phosphate without having to rely on guesswork. With this solution, you can add the precise amount of phosphorus you need to meet the needs of your plants without the risk of overdosing on nitrates. The solution contains 4,500 mg/L of phosphate and is nitrate-free.

When used properly Flourish Phosphorus™ supports the development of plants without promoting algae growth.

Harmless for invertebrates and shrimps.

Recommended use:

Use 2.5 ml Flourish Phosphorus™ per 80 litres of aquarium water once or twice a week. The phosphorus content should be increased by 0.05 mg/L (for reference purposes: ideal phosphate levels are between 0.15 and 1.0 mg/L).

If you are aiming for specific values, you can use the following dosing formula: 0.8vp=m (v = tank volume in gallons, p = desired phosphate increase, m=volume of the product to be used in ml), or you can use the dosing calculator from Seachem to calculate values.

It can also used if there are visible signs of phosphate deficiency.
