Seachem Flourish Nitrogen

Seachem Flourish Nitrogen is a nitrogen supplement for planted aquariums that provides both nitrate and ammonium forms of nitrogen to support plant growth.

  • Nitrogen supplement for the planted aquarium
  • 15,000 mg/L blend of nitrogen sources
  • Provides nitrogen in both the nitrate form and the ammonium form.

Seachem Nitrogen is one of the main three macronutrients (nitrogen, phosphorus, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the plant–preferred ammonium form. However, no free ammonia is released because the ammonium in Flourish Nitrogen™ is complex and unavailable until utilized by the plants. Flourish Nitrogen™ also provides nitrate for those plants that can readily utilize nitrate as well. For maximum benefit, use with Flourish Phosphorus™ and Flourish Potassium™. Flourish Nitrogen™ is safe for invertebrates such as shrimp.

Directions

BEGINNER: Use 2.5 mL (half a cap) for each 160 L (40 US gallons) twice a week or as needed in response to signs of nitrogen deficiency (e.g. stunted growth, chlorosis). For smaller doses, please note that each cap thread is approximately 1 mL.

EXPERT: The beginner dose raises nitrogen by the same degree that 1 mg/L nitrate would. This dose is sufficient to provide approximately 4 g of growth (dry) or about 20 g (hydrated) over a 1 month period (assuming all other necessary nutrients are provided). For increased growth use proportionately more.

To target a specific nitrogen increase, dose according to the following formula: 0.25vn=m, where v= volume of tank in gallons, n=desired nitrogen increase (if using a “nitrate equivalent” value for “n” then use a factor of 0.05 instead of 0.25 in the formula) and m=volume of product to use in mL. For example to raise 20 gallons by 0.20 mg/L nitrogen you would use: 0.25*20*0.20=1 mL.

Because one-half of the nitrogen in Flourish Nitrogen™ is from nitrate you can get a reasonable estimate of nitrogen levels by doubling a nitrate reading.

Wrapped in luxury
Color: Cream (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
I went through a lot of faux fur throws and blankets to find this gem. It’s double sided fur and very warm and cozy. My only gripe is that it’s not wider but it measures true to its size. It’s super soft and fluffy. Would highly recommend this blanket as you’ll be wrapped in luxury.

Amazing and luxurious
Color: Cream (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
My daughter said this blanket can be described as luxury. It is soft, plush, and warm. It does slip and slide some, so just be aware that it can do that

Super soft, looks and feels lovely
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
LThis is a double sided faux fur blanket (with sides have the same slightly bubbled fur. It iz slightly bubbled looking, not as bubbly as the picture makes it seem. The two sides are sealed around the edge, but not sewn or tied in anyway throughout the blanket, so the two sides are free to move on theinside of the. Blanket. It is extremely soft, and my dog, who is old and going blind actively seeks out this particular blanket to make his nest in. He loves it, and so do I. I got it discounted in white, a d know at some point it won't look white any.ore. I'll try to die it after it gets a little grungy looking. Till then, it looks and feels luxurious. I only wish it were joined together in the middle, and more "bubbly" looking. It's a bit heavy by itself for summer nights, but feels warm down cozy in colder times. I got the throw size, it seems a bit smaller than I expected it to be.

Warm and cuddly!
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
I love this double sided blanket!! It is sooo soft and warm. I got the creme color. I don’t understand the reviewers that say that it is hard to fold or that it slips against itself. Mine has two edges/seams that are sewn well and it’s simple to fold after use. I just look for the tag which is on one seam and fold from there. Great buy too!!
