Seachem Reef Complete™
Seachem Reef Complete Seachem Reef Complete™ 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 importantelements 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. 500 mL treats 8,000 L (2,000 gallons).

Seachem Reef Calcium™
Seachem Reef Calcium 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 Kalkwasser™
Seachem Reef Kalkwasser 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.
