Seachem StressGuard is a premium slime coat protector for marine and freshwater aquariums. Using a unique formula, StressGuard reduces fish stress from transportation or handling, promotes healing, and acts as an antiseptic to reduce the risk of infection.

• Premium slime coat protection product for fresh and saltwater aquariums
• Reduces stress when handling or transporting fish
• Promotes healing and acts as an antiseptic for fish

StressGuard is compatible with all non-copper based medications. It is not amine-based and will not interfere with Purigen or HyperSorb, and does not coat resins or clog filtration like other slime coat products can.

What sets StressGuard apart The secret is a protein active colloidal agent that actively seeks out any wounds, abrasions, or exposed proteins, and attaches to the area to deliver disinfectant and begin healing. In the process, the agent also acts as a liquid bandage to keep the abrasion protected. And unlike other slime coats, StressGuard has a pH of 7.0 - meaning it will never interfere with the pH of your aquarium, even when used in large doses.

Directions: Use 1/2–1 capful (2.5–5 mL) to every 10 gallons (40 L) daily until signs of stress have abated or healing is complete. Dose may be safely doubled.

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.

Seachem Flourite is an all natural porous clay gravel substrate, specially broken and mineral-enriched to enhance live aquarium plant growth. It requires no gravel modifiers and never needs to be replaced, remaining effective for the life of the aquarium.

• Premium natural substrate for the planted aquarium
• Good for life of aquarium, no replacement necessary
• All natural porous clay composition

Though its appearance is best suited for planted aquariums, Flourite may be used in any aquarium. It is most effective when used alone as an integral substrate bed, but it may also be mixed with other gravels. Flourite is not chemically coated or treated, and will not alter the pH of your aquarium water.

Directions: Flourite is pre-washed, but may be rinsed before use to remove any residual dust. Residual dust can also be minimized by filling the aquarium slowly while evenly dispersing the water to avoid disturbing the Flourite bed. Some slight initial cloudiness is normal and will clear quickly, within 2-12 hours. Mechanical filtration and Seachem Clarity can be used to resolve cloudiness even more quickly.

Tip: To minimize cloudiness from residual dust, place Flourite in a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed.

Note: This package does not feature a mesh bottom.

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 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).

Equilibrium is specifically designed to establish the ideal mineral content for the planted aquarium. Equilibrium contains no sodium or chloride (which can be detrimental to a planted aquarium at elevated levels). Equilibrium is ideally suited for use with RO (reverse osmosis) or DI (deionized) water or any mineral deficient water. Equilibrium raises the essential mineral/electrolyte content (General Hardness) of the water to balance with and promote stability of the carbonate hardness. To maintain KH, we recommend Alkaline Buffer. Equilibrium contains NO SODIUM CHLORIDE. Both sodium and chloride are not rapidly depleted elements in a planted aquarium, and, in the case of chloride, can do more harm than good. Also, sodium is not a contributing cation to GH levels. Equilibrium contains only calcium, magnesium, and potassium salts, which aid in fish metabolism but are also highly beneficial to plant growth. Equilibrium guaranteed analysis and symptoms of deficiency

• Restores and Maintains Mineral Balance and GH
• Contains No Sodium or Chloride
• Fast Dissolving Powder Repaces Minerals for Healthy Plant Growth
• Reverse Osmosis Water Conditioner for Freshwater Planted Aquariums
• Made in the USA

INSTRUCTIONS: 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). For optimum solubility, we recommend mixing with 1 L (1 qt.) of water (the resulting mixture will have a white opaque appearance). When this mixture is added to the aquarium it will impart a slight haze that should clear within 15-30 minutes. HINTS: Do not use Equilibrium when replacing evaporated water. This dose is based on DI or RO water; for other water, measure hardness (GH) first, then add according to need. For precise dosing, use the Seachem Digital Spoon Scale. Plant preferences vary, but a general guide is about 1-2 meq/L (3-6 dH) or match the existing or target carbonate hardness (KH), which, ideally, is also about 1-2 meq/L (3-6 dKH). Equilibrium will compact with age, but remains effective.

Prime is safe for fresh and saltwater aquariums. It detoxifies ammonia, nitrite and nitrate, allowing the biofilter to more efficiently remove them. Use Sechem Prime to detoxify any heavy metals found in the tap water at typical concentration levels. Prime also promotes the production and regeneration of the natural slime coat. Seachem Prime is non-acidic, will not impact pH and will not overactivate skimmers.

Use at startup and whenever adding or replacing water. Prime may also be used during tank cycling to alleviate ammonia/nitrite toxicity.

Directions: Use 1 capful (5 ml) for each 200 L (50 gallons) of new water. This removes approximately 1 mg/L ammonia, 4 mg/L chloramine, or 5 mg/L chlorine. For smaller doses, please note each cap thread is approx. 1 ml.

Tips: May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.

Reef Strontium's addition to reef aquariums aids the growth of corals, coralline algae, and other organisms that lay down a calcareous skeleton or shell, including tridacnid clams. Reef Strontium is intended to restore and maintain strontium to levels found within natural seawater without affecting pH. Strontium is utilized in the same manner as calcium and holds a similar importance in maintaining a vigorous level of growth.

• Seachem Reef Strontium aids in healthy growth of corals and coralline algae
• Restores and maintains strontium in reef aquariums
• Gluconate complexation provides a rich source of metabolic energy

Reef Strontium contains 10,000 mg/L of available strontium as a gluconate complex. Gluconate complexation offers several benefits: it increases the bioavailability of the strontium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it inhibits strontium precipitation/alkalinity depletion. Gluconate does not contain nitrogen or phosphorus, making it biologically impossible for it to lead to algae growth in a properly maintained reef system.

DIRECTIONS: Use 1 capful (5 mL) per 80 L (20 US gallons) twice a week.

Seachem Reef Builder supplies the carbonates and calcium which are essential for all coral growth. It also raises carbonate alkalinity without immediately impacting water pH, and will stabilize aquarium water at pH 8.3 with long term use.

• Raises carbonate alkalinity (KH) with minimal pH impact
• Provides a blend of carbonate sources that will not lower pH
• Will not deplete calcium, magnesium, or strontium
• Promotes healthy coral growth

If either calcium or carbonates become deficient, coral growth will cease, followed by a rapid decline in coral health. Used as directed, Seachem Reef Builder will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity.

Seachem Reef Builder and Reef Buffer may be used together: use Reef Builder to raise carbonate alkalinity without affecting pH, and use Reef Buffer to raise carbonate alkalinity and pH. As a general rule, reef alkalinity should be maintained at 3–5 meq/L (8–14 dKH); alkalinity should not be allowed to fall below 2 meq/L.

Directions:
BEGINNER: Use 3 g (1/2 level teaspoon) per 150 L (40 gallons) twice a week. Dissolve in at least 250 ml (1 cup) of freshwater. Check alkalinity every 2 weeks and adjust amount or frequency accordingly. For precise dosing, use the Seachem Digital Spoon Scale.

ADVANCED: Check alkalinity, then follow addition regimen above until alkalinity is adjusted to 4–5 meq/L. Each 3 g/150 L will raise alkalinity by about 0.25 meq/L. Quantity or frequency can be adjusted, but do not exceed 12 g/150 L per day. Thereafter, use as required to maintain alkalinity.

EXPERT: After determining the alkalinity consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top–off water: m=0.08va (m=grams to add to top off water, v=volume of tank in liters, a=amount to raise alkalinity in meq/L). For example, if you want to raise your alkalinity by 1 meq/L in a 200 liter tank, then you would add 0.08x200x1=16 g into the top–off water. [For reference: 1 gallon=3.8 liters, 6 g=1 teaspoon].

DO NOT OVERDOSE: Excess alkalinity may enhance the loss of calcium, magnesium, and strontium. Do not directly mix with any calcium, magnesium, or strontium supplement. Best if calcium and carbonate additives are added on alternate days or at least 30 minutes apart.

Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system.

• Maintains calcium
• Accelerates coral growth
• Will not alter pH

Reef Calcium may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement. Reef Calcium is intended to maintain calcium levels; if calcium becomes seriously depleted one should either perform a water change or use an ionic calcium supplement to restore the depleted level of calcium.

Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Additionally, polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Reef Calcium utilizes a chained organic calcium rather than an ionic calcium. When a coral absorbs a molecule into its tissue, it uses the same amount of energy regardless of molecular size. However, charged molecules require more energy. When an uncharged molecule of Reef Calcium is absorbed, the coral acquires multiple calcium atoms as well as an easily metabolized carbohydrate with less energy expended than it uses for ionic calcium uptake. Therefore, at lower calcium levels, corals can still take in as much calcium through our organic chains as they would at much higher levels of ionic calcium.

• Increases the bioavailability of the calcium
• Provides a rich source of metabolic energy
• Maintains peak coral growth
• Prevents calcium precipitation/alkalinity depletion
• Will not lead to algae growth in a properly maintained reef system

Directions: Add 1 capful (5 mL) per 80 L (20 US gallons) twice a week. You can increase the amount or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons) per day. Each capful will raise calcium by about 3 mg/L.

Seachem Marine Buffer will safely raise the pH of saltwater to 8.3, and will not raise the pH above 8.3 even if overdosed. Marine Buffer is a blended product, and contains sodium, magnesium, calcium, strontium, and potassium salts to provide effective results.

• Safely raises and maintains saltwater pH to 8.3
• More stable than sodium bicarbonate or sodium bicarbonate substitutes
• Will not raise pH above 8.3 even if inadvertently overdosed

Seachem Marine Buffer is not just sodium bicarbonate or sodium carbonate (commonly sold as a substitute), as these products can raise pH to dangerous levels if not used properly. Instead it includes a variety of minerals and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate for safe, accurate dosing.

Directions: Add 5g (1 level teaspoon) for each 20 gallons (80 L). Dissolve in at least one cup of freshwater. This dose will also raise alkalinity by about 1 meq/L. Add daily until pH stabilizes at 8.3. This will take from a day to a week, depending on original pH and alkalinity. Thereafter, use biweekly or monthly to maintain a pH of 8.3. If this practice is not adequate, then overstocking, overfeeding, or other poor management practice should be sought as a likely cause. In ionically balanced marine water, Marine Buffer produces little precipitate or cloudiness. If an extensive precipitate forms upon addition of Marine Buffer that does not dissolve within about 15 minutes, then poor ionic balance was present. A water change should be initiated when convenient before further use of the product. Effectiveness improves with continued use. Do not directly mix with any calcium, magnesium, or strontium supplement.

ADVANCED: Check calcium level, then follow addition regimen above until calcium is adjusted to 380–420 mg/L. Each 5 g/150 L will raise calcium by about 12 mg/L. Quantity or frequency can be adjusted, but do not exceed 10 g/150 L per day. Thereafter, use as required to maintain calcium.

EXPERT: After determining the calcium consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=vc/400 (m=grams to add to top off water, v=volume of tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 gallon=3.8 liters, 5 g=1 teaspoon].

DO NOT OVERDOSE: Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium and carbonate additives are added on alternate days or at least 30 minutes apart.

Ingredients: Calcium Chloride, Magnesium Chloride, Strontium Chloride.

Guaranteed Analysis:
Calcium (Ca) (min) - 335 mg; (max) - 347 mg
Magnesium (Mg) (min) - 17 mg
Strontium (Sr) (min) - 0.34 mg

Seachem Reef Advantage Calcium is a non-caustic (pH 8.3-8.6) optimized blend of ionic calcium designed to restore and maintain calcium levels to those found in natural seawater. Note that if either calcium or carbonates become deficient, coral growth will cease, followed by a rapid decline in coral health.

• Raises calcium to natural seawater levels
• Capable of raising 20 gallons of water by 25 ppm of calcium with only 1 teaspoon
• Non-caustic and pH balanced (pH 8.3-8.6)
• Maintains magnesium and strontium, will not deplete alkalinity

In addition to calcium, Reef Advantage provides magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr), helping to maintain three critical elements at once. Unlike limewater (kalkwasser), Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. When used as directed, it will not deplete alkalinity.
