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.

Good quality, but a few issues with the hidden mounts and levelness.
Size: 35x7 2Pcs, Color: Black, Size: 35x7 2Pcs, Color: Black
These are quite nice and also sturdy. Only complaint I have is that I bought a couple of these, and on one of them, only one of them, it was difficult to get the hidden mounts to go into the holes. I think it was probably a manufacturing defect thing. Also, on that particular one, it wasnt as level as the other. Not a show stopper, but if you need a perfectly level type of mounting situation, I would be careful here.
