Brightwell Calcion Powder

$ 14.89

Brightwell Calcion Powder Product Overview:

• High-purity powdered calcium.
• Increases the concentration of calcium in marine aquarium water to provide corals and other reef-building invertebrates with one of the most important elements required for growth.
• Stronger and more economical than liquid calcium solutions; created for hobbyists maintaining multiple reef aquaria.
• Formulated by a marine scientist.
• It is recommended that the calcium concentration in the aquarium be determined by using an accurate test kit prior to supplementing. Do not add this product directly to an aquarium containing live animals without first diluting in water as directed.

Technical Background

Calcium is required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies. In reef aquaria, maintaining calcium within a range of 412 - 450 ppm will enable corals and other reef-building invertebrates to grow rapidly when all other physical and chemical requirements are met. [Magnesium, strontium, and carbonate ions are also complexed into aragonite, and their importance in a reef aquarium cannot be overstated.] The rate at which calcium is extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of calcium supplementation.

CaribSea Purple Up Coralline Algae Accelerator

$ 12.89

PurpleUp™ uses a unique dual method approach to coralline algae acceleration. This approach is so unique that PurpleUp™ has been awarded a US patent (US patent No. 7,565,883). It contains ionic calcium, which immediately raises dissolved calcium levels in your aquarium water. At the same time Super Sea Calcium™ (a 10 micron aragonite powder derived from natural seawater) targets the live rock surface. This dissolves in situ, delivering calcium, strontium, magnesium, and carbonate right where it’s needed. PurpleUp™ also replenishes iodine, an essential element for coralline algae tissues that quickly becomes depleted in closed systems. PurpleUp™ is not a fertilizer, it does not promote the growth of nuisance algae.

Available Sizes:

• 16oz
• 1 Gallon

Continuum Aquatics Coralline Purple CX

$ 7.85

Continuum Aquatics Coralline Purple C is specifically designed to encourage and accelerate growth of purple and pink coralline algae without fertilizing green algae. Because it is made from expensive marine aragonite, with added supporting minerals, it will not pollute your system like inexpensive aquatic muds of terrestrial origin may. It is phosphate and nitrate free.

Coralline Algae is not only beautiful in the marine aquarium, it takes up the space where unwanted organisms might normally grow. Because coralline algae is alive, it must be introduced into the aquarium by the addition of small pieces of live rock upon which it is already growing. This doesn't take much. You may be able to get many different types growing on small chunks at your local aquarium store. Some coralline algae will grow with little or no lighting, while others seem to enjoy strong reef lighting. It is evident that lighting does play some role, so you should experiment with it. It is important to measure phosphates and keep the level as low as possible to encourage coralline algae growth. Continuum also recommends that you maintain a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm).

Available Sizes:

• 250 ml
• 500 ml
• 2 L

Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L). Addition of Coralline Purple CX at night will help balance pH and prevent night time pH decline. It will also allow time for the water to clear from the cloudiness that is inherent in dissolving the aragonite particles in the product.

Directions: Coralline Purple CX will cloud the aquarium upon addition, it is therefore recommended that it be added a night in an area of strong flow. Shake vigorously immediately prior to use! Add 1 capful (5 ml) per 25 US-gallons (100 L) of marine aquarium water 3 to 4 times per week. Coralline Purple CX will raise the calcium level in your aquarium. For best results, measure the calcium concentration and add as required to maintain the concentration between 410 and 450 mg/L (ppm).

This product is not suitable for use in most dosing systems because of the need for agitation, and should be added manually. Daily addition is preferable, though. Do not mix with any other supplements prior to addition.

Caution: Keep out of reach of children. Not for human consumption. Contains powdered aragonite and mineral salts, if ingested drink water. If in eyes flush with water for 15 minutes. If redness persists consult your healthcare practitioner.

Continuum Aquatics Reef Basis Calcium

$ 7.89

Continuum Aquatics Reef Basis Calcium is a high quality, maximum strength ionic calcium solution designed to safely raise the calcium level in marine aquariums, providing essential calcium for increased growth rates in corals, coraline algae, crustaceans and many other marine organisms. It contains no acetate, gluconates, polygluconates or other unnecessary organics to pollute your aquarium. It is phosphate and silicate free. May be used simultaneously with Kalkwasser.

Proper control of calcium level is imperative for the health and growth of corals and many other invertebrates. If the calcium concentration is too low, growth rates will suffer. If it is too high, alkalinity or buffering capacity will be diminished, leading to possible instability of pH. Sufficient magnesium levels are also necessary to maintain the proper balance. It is therefore recommended that the hobbyist measure and control the levels of calcium, magnesium and alkalinity on a regular basis. Strontium is also required for formation of aragonite. Continuum recommends that you maintain a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm). Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L). Do not add calcium and buffering (alkalinity) products at the same time. Doing so will cause unnecessary precipitation and possible cloudiness.

Directions: Shake well prior to use. Add 1 capful (5 ml) per 50 US-gallons (200 L) of marine aquarium water 3 to 4 times per week. For best results, measure the calcium concentration and add as required to maintain the concentration between 410 and 450 mg/L.

Red Sea Coralline Gro - Live Rock Vitalizer

$ 12.99

Red Sea Coralline Gro - Live Rock Vitalizer Overview

Coralline algae will grow naturally, without any special supplements in all reef systems optimized for hard corals. To promote coralline algae in fish only or soft coral aquariums the alkalinity needs to be maintained at approximately 3 meq/L ( 8.4 dKH ) and specific minor and trace elements need to be readily available.

• KH Coralline Gro is a complex of carbonate buffers, potassium and trace elements such as iron, formulated in the ratio taken up regularly by the coralline algae. 
• KH Coralline Gro should be used instead of Reef Foundation B (buffer) supplement during the cycling of all new marine aquariums and on an ongoing basis in fish-only or soft corals systems.
• KH Coralline Gro should be dosed according to a measured drop in alkalinity with Red Sea's Reef Foundation KH/Alkalinity Pro Test Kit.

Concentration Liquid supplement:

1ml will raise the Alkalinity level of 100 liters (25 gal) by 0.1 dKH (0.03 meq/l).

Red Sea Reef Foundation A Liquid Supplement (CA)

$ 14.99

A successful coral reef aquarium depends on how well you maintain the water parameters which are the key to a stable coral environment. All of the elements found in natural seawater play a role in providing optimal water parameters, but some are more significant than others. These elements, the foundation of the reef environment, include the three major elements: Calcium (Ca), Magnesium (Mg) and Carbonates (CO3). All three have a major effect on water chemistry (pH stability, Alkalinity, ionic strength) and on many of the corals' biological processes (skeleton formation, ions exchange, photosynthesis). The foundation elements complement each other in the formation of coral skeleton. If not balanced correctly one of the elements will quickly limit healthy coral growth. Maintaining balanced levels of the Foundation Elements (Ca, KH & Mg) creates optimal water conditions for promoting strong and healthy coral growth. Reef Foundation A is a Calcium & Strontium complex for balanced formation of Coral Skeleton. Reef Foundation A: Contains Calcium, Strontium, and Barium according to the ratios found in coral skeleton.

Red Sea Reef Foundation A Supplement (CA) sizes: 500mL, 1 L

Concentration: 1ml will raise the Ca level of 100 liters (25 gal) by 2ppm.

Red Sea Reef Foundation ABC+ Supplement (Ca/Sr/KH/Mg/K/Br)

$ 21.99

Calcium, magnesium, strontium and carbonate are the basic foundation elements of coral skeletons. All of these elements need to be available in balanced proportions for positive coral health and growth. Reef Foundation ABC+ is a blend of all of the foundation elements with the addition of potassium, bromine and iodine in the unique ratio required by corals.

Red Sea's Reef Foundation ABC+ is a uniquely formulated powder supplement containing all of the elements of Foundation A, B & C, plus Red Sea's Coral Colors A & B (potassium, boron, iodine & bromine) formulated in the exact ratio as found in the coral skeleton. Although there are slight differences between the coral species, the mean ratio between these elements is fairly constant. Supplementing all of these elements in a fixed ratio according to the uptake of calcium will ensure an accurate replenishment based on the metabolic demands of the corals.

Reef Foundation ABC+ should be dosed on a daily or weekly basis according to the aquarium type and according to a measured uptake of calcium. Over time an imbalance may occur between the foundation elements. If dosing daily, you should test all of the foundation elements weekly and make adjustments with the individual A, B & C supplements. If dosing weekly you should test all of the foundation elements monthly and make adjustments with the individual A, B & C supplements.

Seachem Reef Advantage Calcium

$ 7.69

Seachem Reef Advantage Calcium is equivalent to dry Reef Complete. It is a non-caustic (pH 8.3-8.6) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater. 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. Reef Advantage Calcium also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. If either usage or precipitative loss results in a more rapid loss of either magnesium or strontium, then Reef Advantage Magnesium, Reef Advantage Strontium, or Reef Strontium may be employed. Unlike limewater (kalkwasser), Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity. 250 g treats 8,000 L (2,000 gallons).

Seachem Reef Calcium

$ 4.19

Seachem Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH (formulated at pH 8.2). 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 inhibits calcium precipitation/alkalinity depletion. One side benefit includes enhancement of denitrification. 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 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 Complete, Reef Advantage Calcium, Reef Kalkwasser). 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. Each 100 mL treats up to 1,600 L (400 gallons).

Seachem Reef Complete

$ 5.89

Seachem Reef Complete is the liquid version of the Reef Advantage Calcium. It is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH (formulated at pH 8.3). 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. Reef Complete also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. Reef Complete delivers 560x more calcium than is available from an equal volume of kalkwasser solution. Use Reef Complete to maintain adequate calcium and Reef Calcium to promote accelerated growth. 250 mL treats 2,000 L (1,000 gallons).

Seachem Reef Kalkwasser

$ 12.49

Seachem Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. This calcium hydroxide meets or exceeds the purity of competing brands designated for reef use. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that are used in an automated dosing system that replaces evaporated water. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its capacity to perform these functions is dependent on evaporation rate and CO2 concentration. If these two factors are insufficient you can provide additional calcium with Reef Advantage Calcium, Reef Complete, or Reef Calcium, and carbonate alkalinity with Reef Builder or Reef Carbonate (do not mix these directly with a kalkwasser solution). Reef Kalkwasser can also precipitate phosphates and impurities from the makeup water while maintaining a high pH which is important for proper calcification rates and for oxidizing various organics in reef aquaria. 500 g makes 650 L (166 gallons) of kalkwasser solution.
