Seachem

Seachem Prime is the complete and concentrated conditioner for both fresh and saltwater aquariums. Use during startup and water changes to eliminate and detoxify harmful chemicals in tap water and make your aquarium safe for fish.

• Removes chlorine, chloramine and toxic ammonia
• Detoxifies nitrite and nitrate
• Provides protective slime coat

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.

BEGINNER: Use 5 g (1 level teaspoon) per 150 L (40 US gallons) twice a week. For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 ml (1 cup) of freshwater. Check calcium every 2 weeks and adjust amount or frequency accordingly.

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
