Flourish Phosphorus™ is a safe solution (4500 mg/L phosphate) of potassium phosphate that takes the guesswork out of phosphate dosing. Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus™ (being nitrate-free) allows you to dose phosphorus according to the needs of your plants without the risk of overdosing nitrates. When used as directed, Flourish Phosphorus™ will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit, use with Flourish Nitrogen™ and Flourish Potassium™. Why It's Different Unlike competing products, Flourish Phosphorus™ is entirely nitrogen-free, making it possible to adjust the phosphorus level in an aquarium without affecting nitrogen levels. Directions BEGINNER: Use 2.5 mL (half a cap) for each 80 L (20 gallons*) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g., stunted growth, plants dark green). EXPERT: The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary but generally ranges from 0.15–1.0 mg/L. Use MultiTest: Phosphate™ to monitor phosphate levels. To target a specific phosphate increase, dose according to the following formula: 0.8 × v × p = m, where v = volume of tank in gallons*, p = desired phosphate increase, and m = volume of product to use in mL. For example, to raise 20 gallons* to 0.1 mg/L phosphate, you would use: 0.8 × 20 × 0.1 = 1.6 mL.

FAQ (Frequently Asked Questions)

Yes, you can order fish along with dry goods. However, if the dry goods are heavy or bulky, it may be more cost-effective to place two separate orders. In that case, you could ship the dry goods using a slower, more affordable shipping option.

If your order has not shipped yet, you can email us your correct shipping address, and we will update it for you.

On weekdays, if we receive your order before 2 p.m., it will be shipped out the same day. Dry goods are shipped from Monday to Friday. Orders that include livestock are only shipped from Monday to Thursday to avoid transit over the weekend.

At checkout, you can leave your request in the comments box.
