Flourish Phosphorus is a reliable solution (4,500 mg/L phosphate) of potassium phosphate that eliminates the uncertainty of phosphate dosing.


KEY FEATURES:

  • Phosphorus enhancer for your planted aquarium
  • A dependable 4500 mg/L potassium phosphate solution
  • Removes the uncertainty from phosphate dosing

DIRECTIONS:
Beginner:
Administer 2.5mL (half a cap) for every 80L (20 US gallons) once or twice a week, or as necessary based on signs of phosphorus deficiency (e.g. stunted growth, dark green plants).

Expert:
The beginner dosage increases phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The optimal phosphate level can differ, but typically falls between 0.15-1.0 mg/L.

To achieve a specific phosphate increase, apply the following formula: 0.8vp=m, where v= tank volume in gallons, p=desired phosphate increase, and m=amount of product to use in mL. For instance, to elevate 20 gallons to 0.1 mg/L phosphate, you would calculate: 0.8*20*0.1=1.6 mL.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves!
Size: 24x5.8, Color: Black, Size: 24x5.8, Color: Black
I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.
