Flourish Nitrogen is a potent (15,000 mg/L) mix of nitrogen sources. It delivers nitrogen in both the nitrate form and the ammonium form that plants prefer.


KEY FEATURES:

  • Nitrogen booster for your planted aquarium
  • 15,000 mg/L blend of nitrogen sources
  • Supplies nitrogen in both nitrate and ammonium forms

DIRECTIONS:
Beginner
Administer 2.5mL (half a cap) for every 160L (40 US gallons) two times a week or as required based on signs of nitrogen deficiency (e.g., slow growth, yellowing leaves). For smaller amounts, be aware that each cap thread is roughly 1mL.

Expert
The beginner dosage increases nitrogen by the same amount as 1 mg/L nitrate would. This dosage is adequate to facilitate approximately 4g of dry growth or around 20g (when hydrated) over the course of a month (assuming all other essential nutrients are supplied). For enhanced growth, use a proportionately larger amount.

To achieve a specific nitrogen increase, follow this formula: 0.25vn=m, where v= tank volume in gallons, n=desired nitrogen increase (if using a "nitrate equivalent" value for "n", utilize a factor of 0.05 instead of 0.25 in the formula) and m=amount of product to apply in mL. For instance, to elevate 20 gallons by 0.20 mg/L nitrogen, you would calculate: 0.25*20*0.20=1mL.

Beautiful Decorative and Light Weight Shelving!
Color: White
Beautiful shelving. Came with hardware for hanging and a ruler strip template for mounting locations, although the holes did not match up with the shelf holes. Shelves are just the right size for my purpose and also decorative and light weight.

sturdy, solid wood, a couple of blemishes
Color: Black
The shelves are securely packed for shipping. The box for the actual item was dented and smashed at one corner, but the contents were well secured. The support braces (6 in total) had a blemish on one - which I will cover with black permanent marker and face on the inside. The second support, which was packed so one could see the defect upon opening of the box, had a couple of dings on the top of the shelf and a huge notch taken out of the side of the support - which is black and near the top and shouldn't be noticable. I question the quality control to ship out that piece with the serious notch, especially because it was right on top when you opened the box, fully visible. I originally thought it was an angled hole for a screw, until I read the instructions and then realized the others didn't have that notch. The 3 shelves are fine except for the one with a few small dings/dents on the top side. The set comes with dowels, all hardware and so forth. Overall these are solid sturdy shelves.
