Seachem Flourish Advance ('116123600)

Seachem Flourish Advance is an all natural growth enhancer for live aquarium plants, with an enhanced formula that uses phytohormones, minerals, and nutrients to stimulate dramatic growth in roots and shoots. When used regularly, it also heightens mineral absorption and disease resistance.

  • Natural phytohormone supplement for the planted aquarium
  • Dramatically stimulates the growth of roots and shoots in aquatic plants
  • Enhances mineral absorption and improves disease resistance
  • Non-toxic and completely safe for all plants, fish and aquatic organisms

What makes it special Phytohormones give Flourish Enhance an edge over other aquarium plant growth enhancers. They are naturally occurring compounds that play important roles in regulating plant growth in a wide variety of processes, including cell division, formation and activity of shoot meristems, induction of photosynthesis gene expression, leaf senescence, nutrient mobilization, seed germination, root growth, and stress response.

For ten to fourteen days after application, Flourish Advance stimulates root growth beneath the surface. After this initial induction period, significantly enhanced growth in the leaves and stems of the plants will occur.

Directions: Shake well before use. Use 1 capful (5 mL) for every 80 L (20 gallons). Dose daily or as required to maintain plant growth.

Seachem Flourish Iron Supplement
Seachem Flourish Iron Supplement ('116047609)

Seachem Flourish Iron is a highly concentrated iron supplement for aquariums with live plants. Its simple, pure formula is ideal for iron deficiencies and/or situations when iron requirements are greater than what Seachem Flourish can provide.

  • Iron supplement for the planted aquarium
  • Highly concentrated (10,000 mg/L) ferrous iron
  • Contains no phosphate or nitrate

Flourish Iron contains 10,000 mg/L of ferrous iron (Fe+2) gluconate, a highly effective form of iron that provides greater benefits than ferric state EDTA-iron (Fe+3) sources used in other iron supplements. Plants can only utilize iron in the ferrous state, and must expend extra physiological energy just to make ferric iron supplements usable. Flourish Iron provides plants the iron they need directly, saving time and reducing stress on your plants.

Use Flourish Iron in those cases where iron requirements exceed that which can be delivered by standard Seachem Flourish at the recommended dose, or when signs of iron deficiency appear (including short, slender stems or yellowing between veins).

Directions: Use 1 capful (5 mL) for each 200 L (50 gallons) of water, 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 a test kit to monitor iron concentrations. Use as needed to combat signs of iron deficiency (usually seen in new growth).

Seachem Flourish Phosphorous
Seachem Flourish Phosphorous ('116019309)

Seachem Flourish Phosphorus helps accelerate and enhance the growth of live aquarium plants, without contributing to nuisance algae growth. This simple, safe solution contains no nitrates, allowing precise phosphorus dosing to meet your plants' needs.

  • Phosphorus supplement for the planted aquarium
  • Safe solution (4,500 mg/L) of potassium phosphate
  • Contains no nitrate and does not contribute to algae growth

Flourish Phosphorus supplies an ideal concentration (4,500 mg/L) of phosphorus, one of the three macro nutrients required for healthy plant growth (the others are nitrogen and potassium). Unlike competing products, it is nitrate-free and allows you to accurately dose your aquariums phosphate levels without the risk of overdosing nitrates. Use Flourish Phosphorus along with Flourish Nitrogen and Flourish Potassiumto achieve an ideal ratio of all three nutrients.

Directions:
Beginner: Use 2.5 mL (half a cap) for each 80 L (20 gallons) once ot twice a week or as needed in response to signs of phosphorus deficiency (such as stunted growth and/or very dark green coloring).

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 a reliable test kit 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: 0.8x20x0.1=1.6 mL.

Seachem Flourish Potassium
Seachem Flourish Potassium ('116046602)

Seachem Flourish Potassium provides concentrated potassium to support vigorous growth in aquariums with natural, living plants. This safe, effective supplement helps you avoid potassium depletion, yellowing leaves, and limited plant growth.

  • Potassium supplement for the planted aquarium
  • Helps maintain a vigorous level of plant growth
  • Helps resolve yellowing, death/browning and weak stems and roots

Flourish Potassium contains 50,000 mg/L of potassium - one of the highest concentrations available. Water with low mineral content or systems with rapidly growing live plants can quickly deplete available potassium, causing potassium to become the limiting factor for further growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.

Potassium is most easily obtained from potassium nitrate and potassium phosphate, both of which add either nitrogen or phosphorus to the water and make it more difficult to maintain a specific NPK ratio. However, Flourish Potassium is derived from potassium sulfate, which lets you adjust potassium levels without affecting your tanks nitrogen or phosphorus.

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).

Seachem Flourish Tabs
Seachem Flourish Tabs ('116050500)

Seachem Flourish Tablets are rich in essential trace elements, amino acids, vitamins, and minerals to stimulate healthy growth in aquatic plant roots. They contain no phosphate or nitrate and do not support the growth of nuisance algae.

  • Gravel bed supplement for the planted aquarium
  • Growth stimulating tablets for plant roots
  • Source of micro elements, trace elements and other essential nutrients

These convenient tabs are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that are beneficial for aquatic plant roots. They're an ideal aid for the beginner, with all the nutrients found in Seachem Flourish compressed into an easy-to-use, pre-dosed tablet. Once inserted into the gravel, Flourish Tabs provide direct, time-released fertilization to the root zone. Roots then perform enzymatic action on the tabs, slowly releasing nutrients in healthy doses. Ten tablets will treat a 12"x30" plant bed twice. For best results, use in combination with Flourish.

Directions: Insert one Flourish Tab in the gravel for every 10-15 cm (4"-6") radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed. Add new tablets once every 1-3 months for optimal plant growth. Tabs will not alter pH, but, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.
