6. Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 10 ct
GROWTH TREATMENT: Seachem Flourish Tabs are growth stimulating tablets for plant roots which contain essential trace elements, amino acids, and vitamins.
VITAMINS: Seachem Flourish Tabs 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.
NUTRIENTS: When inserted into the gravel, Seachem Flourish Tabs provide direct, time-released fertilization to the plants’ root zone. Nutrients are slowly made available through enzymatic action of the plants’ roots on the tabs.
TANK USE: Insert one Flourish Tab in the gravel for every 10–15 cm (4–6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed, pushing each tablet midway into the gravel bed.
COMPLETE MAINTENANCE: For optimal plant growth, add new Flourish Tabs to the aquarium once every three to four. Seachem Flourish Tabs will not alter pH, however, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.
7. Seachem Equilibrium 300gram
MINERALS: Equilibrium is specifically designed to establish the optimal mineral content for the planted aquarium. When this mixture is added to the aquarium it will impart a slight haze that should clear within 15–30 minutes.
EQUILIBRIUM: Does not contain sodium or chloride (which can be detrimental to a planted aquarium at elevated levels).
SUITED FOR: Equilibrium is preferably suited for use with RO (reverse osmosis) and DI (deionized) water or any mineral deficient water.
BALANCE: Equilibrium raises the essential mineral/electrolyte content (General Hardness) of the water to balance with and promote stability of the carbonate hardness.
DIRECTIONS: To raise mineral content/general hardness (GH) by 1 meq/L (3 dH), add 16 g (1 tablespoon) for every 80 L (20 US gallons) when setting up an aquarium or when making water changes (add to new water). It is normal for this product not to dissolve right away and it will not harm the tank. It will dissolve over the course of about 12 hours.

35. Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 500 ml
CARBON PRODUCTION: All plants require a source of carbon, and Flourish Excel is a great and convenient source of bioavailable organic carbon.
IRON PRODUCTION: Flourish Excel also possesses iron reducing properties, thus promoting the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).
PHOTOSYNTHESIS: Plants must produce longer chain carbon compounds (photosynthetic intermediates). By dosing with Flourish Excel you bypass the involvement of chain carbon compounds, and introduce the already finished, structurally similar compounds.
TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.
SAFETY: Flourish Excel is completely safe for fish, however if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.

37. Flourish Potassium, 50 mL / 1.7 fl. oz.
CONCENTRATED: Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is vital when maintaining a vigorous level of growth in a planted aquarium.
SUPPLEMENT: Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content.
USE: Flourish Potassium is used to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.
POTASSIUM: Flourish Potassium is derived from potassium sulfate, which allows the user to adjust potassium levels without affecting nitrogen or phosphorus.
DIRECTIONS: Use 1 capful (5 mL) for every 125L (30 US 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.
