Seachem Reef Fusion 1 provides your corals with 100,000 mg/L of ionic calcium, as well as biologically appropriate levels of magnesium, strontium, boron, manganese, and molybdenum. This ionic calcium supplement will bond with a variety of particles in your aquarium, helping your corals receive the necessary calcium for healthy growth.

• Provides 100,000 mg/L ionic calcium for coral growth
• Provides biologically appropriate levels of magnesium, strontium, boron, iron, manganese and molybdenum
• 2-part Reef Fusion system maintains calcium and alkalinity levels

Reef Fusion 1, when used in conjunction with Seachem Reef Fusion 2, creates a powerful system that helps maintain healthy levels of calcium and alkalinity.

Directions: Dose aquarium every 1-2 days. Shake well before using. Add 1 ml of Reef Fusion 1 per 25 L (6.5 US gallons) of water. (For reference purposes, the cap holds 5 ml.) Add this to a high current area of the tank. Wait a few minutes, then add Reef Fusion 2 in the same manner, 1 ml per 25 L (6.5 US gallons), after shaking well. It is preferred that the two products be added to separate locations in the tank. This dose contributes 4 mg/L of calcium, and 0.176 meq/L of alkalinity. Never mix Reef Fusion 1 with Reef Fusion 2 directly.

Note: Do not exceed a dose of 4 ml in 25 L (6.5 US gallons) per day of each product.

Maintain calcium level between 410-430 mg/L. Maintain alkalinity between 4-6 meq/L. Size or frequency of dose may be increased if dosing regimen is insufficient to maintain calcium and alkalinity in these ranges.

Seachem Reef Carbonate helps raise carbonate alkalinity for reef aquariums. A concentrated optimized blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in the reef aquarium. Calcium and carbonates are essential to all coral growth; If either becomes deficient coral growth will cease followed by a rapid decline in coral health.

• Raises carbonate alkalinity in the reef aquarium
• Concentrated optimized blend of carbonate and bicarbonate salts
• Calcium and carbonates are essential to all coral growth

Used as directed, it will not deplete magnesium or strontium which usually tend to precipitate with increasing alkalinity. 250 milliliters treats 1000 gallons.

Seachem Reef Buffer raises the pH of a reef aquarium to 8.3, without the risk of accidentally raising pH to a dangerous level. It will also raise alkalinity, allowing for greater stability in a reef system where the bioload is significantly greater than in a fish-only aquarium.

• Raises pH and carbonate alkalinity together
• Raises pH to 8.3 without risk of accidentally over-raising
• Allows for greater pH stability in reef systems with high bioload

Reef Buffer will raise pH and carbonate alkalinity. However, it is intended primarily to maintain a steady pH of 8.3 when pH maintenance is difficult. If pH maintenance is not an issue, Seachem Reef Builder or Reef Carbonate should be your first choice to supplement carbonate alkalinity.

Reef Buffer has a slightly higher pK than Seachem Marine Buffer. pK of a buffering agent is equivalent to the pH around which the buffer is most effective; Reef Buffers higher pK (8.6) provides greater stability in a reef system, where the bioload is greater than a fish-only system. The higher pK compensates for the organic acids produced by reef inhabitants, holding pH steady at 8.3.

Directions: Check pH and alkalinity before use. Use 5 g (1 level teaspoon) for every 150 L (40 US gallons) to raise pH by about 0.1 pH units (this will also raise alkalinity by about 0.5 meq/L). For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 ml (one cup) of freshwater, then add to the tank. The pH of natural sea water is 8.25–8.30. In a well established reef system, pH adjustment may be necessary biweekly to semiweekly. Dosing requirements will vary, but do not exceed the recommended dose without checking your pH and alkalinity (alkalinity should not exceed 6 meq/L).

If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained or substantial cloudiness that does not clear within 15 minutes is encountered, then the system is not ionically balanced. To restore ionic balance perform a water change or adjust the magnesium and calcium levels to approximately 3:1 Mg:Ca.

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.

Cichlid Trace supplies a broad range of trace elements demonstrated to be necessary for proper sh health and growth. Unlike terrestrial animals, fish obtain nutrients from both their food and environment. Trace elements are normally depleted by utilization, oxidation and precipitation, thus it is important to restore them on a regular basis. Cichlid Trace contains only those elements actually demonstrated to be required by fish.

Reef Trace supplies a broad range of trace elements demonstrated to be necessary for proper reef health and growth. 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. Reef Trace may be used alone or in conjunction with Reef Plus. The best results are obtained when both are used. Reef Trace is nitrate/phosphate free.

• Reef Trace supplies a broad range of trace elements
• Reef Trace may be used alone or in conjunction with Reef Plus

Replenishment of a number of trace elements is required to maintain an environment ideal for the growth and reproduction of marine life, but while the importance of trace elements has been recognized by aquarists for many years, the physiological reasons are not fully understood. The chemical elements in seawater are varied, and, likewise, their addition to the aquarium in trace quantities has varied effects on a variety of saltwater plants and invertebrate species. In general, though, these elements are important for metabolic processes and pigment formation.

DIRECTIONS: Use 1 capful (5 mL) for every 80 L (20 US gallons) twice a week. When used in conjunction with Reef Plus, dose on alternate days.

Reef Phytoplankton is a concentrated blend of green and brown marine phytoplankton designed to provide the essential fatty acids, proteins, vitamins, and amino acids, with biological carotenoids for an invertebrate diet. Size ranges from 1-20 ?m to feed a broad range of tropical marine aquarium filter feeders and invertebrates.

• Reef Phytoplankton is a concentrated blend of green and brown marine phytoplankton
• Phytoplankton size ranges from 1-20 ?m
• Enhanced to increase the bioavailability of important nutrients

IReef Phytoplankton contains a natural source of carotenoids which provides essential proteins as well as a more bioavailable source of pigmentation when compared to other natural sources and synthetic pigments. Carotenoids provide the extra benefit of antioxidant activity. In addition, Reef Phytoplankton is enhanced to increase the bioavailability of important nutrients such as proteins, lipids, B vitamins, and other organic pigments, thus, corals expend less energy to derive the nutritional benefit. It is blended to contain the proper ratio of fatty acids, carbohydrates, and proteins. Blending phytoplankton yields better nutritional value. Studies show increased consumption of phytoplankton in filter feeders when using mixed cultures versus a single culture of phytoplankton.

DIRECTIONS: Shake well before using. Add 1 capful (5 mL) per 200 L (50 US gallons) of water twice weekly or as required to maintain coral growth. For best results, dose directly to the aquarium; target feeding can overwhelm corals and have a negative impact. Refrigeration after opening is recommended, but not required.

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.

Hikari Coralific Delite is a specially formulated food that replaces zooplankton as a nutrient source for your reef aquarium corals. This revolutionary diet offers two modes of feeding: feed directly on the mouth of a specific coral, or "squirt and go," allowing coral polyps to capture the food as they would zooplankton. Either mode offers excellent polyp extension and accelerated coral growth for a stunning aquarium.

• A nutrient package that stimulates feeding response
• Offers excellent polyp extension
• Dual use for maximum feeding flexibility

Coralific Delite contains the necessary nutrients inverts require, specifically: trace elements, proteins, vitamins and astaxanthin for vibrant colors. Its physical properties are similar to those of floating zooplankton, though unlike other powder-type foods, Coralific Delite will not dissolve rapidly or create cloudy water.

Feeding Instructions:
1. Targeted Gel Feeding: Mix two parts tank water to one part Coralific Delite to form a gel. Wait 3 minutes to set then use a dropper to place mixture on the mouth of the coral to be fed. Ideal for many LPS (large polyp stony corals) and sea anemone which have larger mouths.
2. Squirt and Go Feeding: Mix four parts tank water to one part Coralific Delite to form a low viscosity liquid with a creamy texture. Use a dropper to squirt food with a slow motion in the vicinity of the corals to be fed. The viscosity can be adjusted by increasing or decreasing the amount of tank water. Ideal for soft corals like horny coral and feather dusters which have a smaller mouth.

Advanced: Check calcium level (use Reef Status: Calcium to measure calcium), then follow the addition regimen above until calcium is adjusted to 380-420 mg/L. Each 5 mL/80 L (20 US gallons) will raise calcium by about 10 mg/L. Quantity or frequency can be adjusted, but do not exceed 12.5 mL/80 L (20 US gallons) 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 (or skip the math and use our Dosage Calculator) to determine how much to add to your top off water: m=vc/160 (m=mL of product to add to top off water, v=volume of the tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 US gallon=3.8 L].

If used with Reef Calcium, it is not necessary to exceed 380 mg/L total calcium. Use Reef Status: Calcium to measure calcium.

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

INGREDIENTS: Amounts per 1g Calcium (Ca) (min)

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.

API Marine Magnesium Raises Magnesium Levels in Reef Aquariums raises and restores magnesium levels in your reef aquarium, and should be used whenever a magnesium deficiency is present in your water. The magnesium level of a reef aquarium should be between 1,250 to 1,450 ppm. Use API Marine Magnesium when water tests show a magnesium level below 1,250 ppm mg/L in your reef aquarium. Dose according to directions on the product label. Treats up to 948 US gallons of salt water.

• Raise magnesium levels to maintain a thriving reef aquarium
• Dual form of magnesium
• Use whenever testing shows a magnesium level below 1,250 ppm

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 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.

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.
