Product Description Iodide is an important element required by invertebrates and many soft corals (gorgonians, sarcophytons, etc). Reef Iodide™ is a concentrated (8,000 mg/L) stabilized potassium iodide source for reef aquaria that will restore and maintain iodide levels to those found in natural sea water. It is formulated to provide a safe source of iodide that will not convert to toxic free iodine under storage or reef conditions. Iodine is as toxic as chlorine and should never be used in a reef system. However, iodide is as safe as chloride. Most iodine supplements on the market are simply potassium iodide or a medicinal disinfectant commonly known as Lugol’s Solution. Lugol’s is a highly concentrated iodine/iodide solution that is highly toxic and intended for disinfection. Although such products are sold for use in reef aquaria, we believe the risks vastly outweigh the potential minor benefits. Potassium iodide only products are a safer alternative but not very effective alone owing to the unstable nature of iodide in the aquarium environment. When added to an aquarium environment, iodide becomes unstable converting to elemental iodine (which is biocidal), iodate (which is useless to corals, toxic at elevated levels, and can't be tested for), and iodide which is the only form of iodine available to corals for uptake. These products' inherent instability makes them potentially dangerous to coral health. Unlike competing products, Reef Iodide™is complexed to a stabilizing compound in order to keep it in the iodide form when added to the aquarium. All of the product remains usable and fully bio-available. Beginner Add 5 mL (1 capful) for each 200 L (US 50 gallons) every other day. Advanced Add 1 mL for each 80 L (20 US gallons) daily to raise iodide by 0.10 mg/L. If necessary, adjust amount so that iodide reads 0.06–0.08 mg/L 6–12 hours after the last amount. Thereafter, use this amount daily and check iodide twice a month. Expert After determining the iodide 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=0.125vi (m=mL of product to add to top off water, v=volume of tank in liters, i=amount to raise iodide in mg/L). For example, if you want to raise iodide by 0.10 mg/L in a 200 liter tank, then you would add 0.125x200x0.10=2.5 mL into the top-off water. [For reference: 1 gallon=3.8 L].

Product Description Reef Kalkwasser™ is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that will maintain calcium concentrations at natural seawater levels. 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). While Reef Kalkwasser™ is a high purity and economical limewater mix, the beginner, or someone with not as much time to devote to their system, may prefer to use other less involved methods for maintaining proper ionic concentration levels. Never add this product directly to the tank. Add 3 g (1 teaspoon) to 4 L (1 US gallon) of water and mix to dissolve. If using pure water, a fully saturated solution is prepared by adding 6 g (2 teaspoons) to 4 L (1 US gallon). Drip this solution into tank. Monitor pH and carbonate alkalinity. Adjust rate of addition to maintain a stable pH (8.3–8.4). Notes: Adding 4 L (1 US gallon) of a saturated kalkwasser solution to 150 L (40 US gallons) will raise calcium by 24 mg/L. Always use the clear supernatant (top solution) only and do not allow undissolved material to enter the aquarium. Keep this container tightly closed when not in use and minimize solution/air contact to avoid calcium carbonate formation/precipitation.

Product Description Vitality™ is a comprehensive vitamin, amino acid, and trace element supplement developed to address nutritional requirements commonly associated with long term closed system housing of marine ornamental fish. Vitality™ contains ascorbic acid in a heavy base of spirulina and chlorella. Ascorbic acid is a cofactor in the hydroxylation of proline and lysine to components of procollagen, the precursor of collagen, necessary for the formation of connective tissues, scar tissue in wound repair, and bone matrix.* Both spirulina and chlorella contain a rich assortment of amino acids and vitamins. Vitality™ can be used on freshwater ornamental fish; however, it is specifically designed for marine fish. *Nutritional Requirements of Fish, The National Research Council of the National Academy of Sciences, National Academy Press, Washington, DC, 1993, p. 21. Shake well before using. For best results, soak fish food

Product Description Tropic Marin® A- Elements contains a selection of essential anionic trace elements for the promotion of growth and the natural colouring of the corals. Trace elements are natural minerals which are needed by all aquarium inhabitants to maintain biological processes in the cells. Corals and other invertebrates also use large quantities of these minerals for their skeletal development. We recommend the additional use of Tropic Marin® K+ Elements to ensure a complete supply of trace elements (essential cationic trace elements). essential anionic trace elements for corals in liquid form Together with Tropic Marin® K+ Elements, the Tropic Marin® A- Elements supplies a complete profile of the essential trace elements with only two solutions. Tropic Marin® A- Elements contains predominantly anionic trace elements such as iodine, fluorine, bromine, lithium, vanadium, molybdenum and selenium in pure mineral form promotes strong growth and the natural colouring of the corals no colour loss in the corals from trace element deficiency easy to use - suitable for both manual dosage and for dosing pumps
