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.

KEY FEATURES:

• 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

DIRECTIONS:
Beginner
Use 2.5mL (half a cap) for each 160L (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 1mL.

Expert
The beginner dose raises nitrogen by the same degree that 1 mg/L nitrate would. This dose is sufficient to provide approximately 4g of growth (dry) or about 20g (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=1mL.

Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a beneÞt from Flourish Iron because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it.

KEY FEATURES:

• Highly concentrated (10,000 mg/L) iron source for the planted aquarium
• Ferrous gluconate iron
• Ferrous gluconate is better suited to foliar feeding than iron-EDTA

DIRECTIONS:
Use 1 capful (5mL) for each 200L (50 US gallons) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1mL.
