Flourish Excel is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds.

KEY FEATURES:

• Bioavailable organic carbon source for the planted aquarium
• Use as an alternative to CO2 injection or in addition to it
• Introduces photosynthetic intermediates

DIRECTIONS:
On initial use or after a major (> 40%) water change, use 1 capful (5mL) for every 40L (10 US gallons). Thereafter use 1 capful for every 200L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1mL.

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 Trace 250ml  supplies a broad range of trace elements demonstrated to be necessary for proper plant health and growth (see below for signs of deficiencies). Trace elements are normally depleted by utilization, oxidation and precipitation.

Key Features:

– Provide a broad range of micro-nutrients (vitamins, amino acids) and micro and trace elements (iron, manganese, nickel, cobalt, etc) that will enhance plant health and growth. Signs of Trace Element Deficiencies.

– Boron: Death of stem and root apical meristem, leaves twisted, young tissue most affected.

– Cobalt: used for nitrogen fixation, same as nitrogen deficiency signs (stunted growth).

– Copper: Young leaves dark green, twisted, wilted, tip remains alive.

– Manganese: Chlorosis of young leaves, with smallest veins remaining green, necrosis between veins.

– Molybdenum: Chlorosis, twisting, death of young leaves.

– Zinc: Reduced leaf size, shortened internodes, chlorosis, spotted leaves, older leaves most affected.

– Nickel: lack of germination or seed formation, required for iron absorption.
