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

KEY FEATURES:

  • Phosphorus enhancement for planted aquariums
  • 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 (such as stunted growth or dark green plants).

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

To achieve a specific phosphate increase, use the formula: 0.8vp=m, where v= volume of the tank in gallons, p=desired phosphate increase, and m=amount of product to apply 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.

Nice room divider
Color: Colorful Landscape, Size: 6 Panel, Color: Colorful Landscape, Size: 6 Panel
I am pleased with this room divider. I was concerned that the art design might look blurry or cheap in person compared to online, but it doesn't. It looks really nice. In fact, I like it so much that I bought a second one as well. It arrived folded up - there is no assembly required - you simply unfold it and place it where you want. It's relatively light weight so it's easy to move. I also like that there is a different artwork design on each side. You have two choices; you can display whichever side you like more.

May cause respiratory issues
Color: Mountains and Waters, Size: 4 Panel
The painting on this panel is beautiful and quality has held up BUT I’m almost certain this contributed to respiratory issues. It was next to my bed for a year and I recently noticed it’s still shedding red/brown dust. The wood was clearly painted over and it makes me skeptical about the wood that was used. The panel itself feels like it’s made cardboard. If you’re sensitive or plan to place this panel in a main living area, I would not recommend

Ideal to hide stuff.
Color: Mountains and Waters, Size: 6 Panel
A really decorative pice for privacy, but I will also purchase the feet separately for sturdiness.

Muted But Pretty!
Color: Mountains and Waters, Size: 3 Panel
Nice, sturdy 3-panel screen/room divider! However, could/should have been priced at $20-30 less. I like that it stands and folds easily, and there is not too much decoration or an exorbitant design. The colors are muted and would work well with many styles or color schemes. Personally, I wanted the wood frame to be a little lighter in color though.
