Flourish Excel
Sea Chem 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 (such as photosynthetic intermediates). Therefore, one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2; injection. Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).Sea Chem Flourish Excel is an integral component of Seachem's plant products and is recommended for use with the entire Flourish line as well as our Flourite and Onyx Sand substrates. Contains no phosphate or nitrate.

Flourish Trace
Flourish Trace supplies a broad range of trace elements demonstrated to be necessary for proper plant health and growth (see right panel for signs of deficiencies). Trace elements are normally depleted by utilization, oxidation and precipitation. The latter two processes occur more rapidly than with other micronutrients. This makes it important to restore trace elements on a regular basis. Flourish Trace may be used alone or in conjunction with Flourish. Best results are obtained when both are used.DIRECTIONS: Use 1 capful (5 mL) for every 80 L (20 gallons*) twice a week.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

Flourish Tablets
Sea Chem Flourish Tablets (10pk) are growth stimulating tablets for plant roots. They contain essential trace elements, amino acids, and vitamins. They are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots.Sea Chem Flourish Tabs contain no phosphate or nitrate that would promote algae proliferation. Each pack of ten tablets treats a 12 X 30 inch plant bed twice. For best results, use in combination with Flourish.Sizes: 1 pack of 10 tablets (3 g each)

Flourish Iron
Flourish Iron is a highly concentrated (10,000 mg/L) ferrous iron (Fe+2) gluconate supplement. It should be used in those cases where the iron requirements exceed that which can be delivered by Flourish at the recommended dose or signs of iron deficiency appear (such as short and slender stems or yellowing between veins.) Plants are able to much more easily derive a benefit from Flourish Iron than from EDTA-iron sources because all EDTA iron is in the ferric (Fe+3) state. Since plants require iron in the ferrous state, additional physiological energy must be expended in order to extract the ferric iron from EDTA-iron and then convert it to the ferrous form. Contains no phosphate or nitrate.DIRECTIONS: Use 1 capful (5 mL) for each 200 L (50 gallons*) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1 mL. Use MultiTest: Iron test kit to monitor iron concentrations. Use as needed to combat signs of iron deficiency (usually seen in new growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.

Flourish Potassium
Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.DIRECTIONS: Use 1 capful (5 mL) for every 125 L (30 gallons*). This dose raises potassium by 2 mg/L. Repeat 2–3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.

Flourish Phosphorus
Phosphorus is one of the main three macro nutrients (nitrogen, phosphorous, potassium: NPK) required by plants and can often become the limiting factor to growth in a nourishing system. Flourish Phosphorus is a safe solution (4500 mg/L phosphate) of potassium phosphate that takes the guess work out of phosphate dosing. Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus (being nitrate free) allows you to dose phosphorus according to the needs of your plants without the risk of overdosing nitrates. When used as directed Flourish Phosphorus will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit use with Flourish Nitrogen and Flourish Potassium..DIRECTIONS: BEGINNER: Use 2.5 mL (half a cap) for each 80 L (20 gallons) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g. stunted growth, plant dark green). EXPERT: The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15–1.0 mg/L. Use MultiTest: Phosphate to monitor phosphate levels. To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of tank in gallons, p=desired phosphate increase and m=volume of product to use in mL. For example to raise 20 gallons to 0.1 mg/L phosphate you would use: 0.8200.1=1.6 mL.
