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® All-For-Reef Powder is an ultra-concentrated mineral blend, with which an easy-to-use, highly concentrated all-round solution for supplying all key minerals and trace elements in newly established and averaged reef aquariums is available after being dissolved in reverse osmosis water. Update: Dark Spots =Iodine per Tropic Marin - Just heard from Tropic marin....the dark spots are Iodine from the new formulation of A4R where they increased this element. Through the growth of organisms and other processes in the aquarium, minerals are consumed and must therefore be supplemented regularly. These include, in particular, the necessary elements calcium, magnesium and strontium, as well as carbonate hardeners for the growth of calcium carbonate skeletons in stony corals, lime red algae and other reef organisms. Tropic Marin® All-For-Reef contains all of these components in a highly concentrated form. In addition, all essential trace elements are also included: Iodine, bromine and fluorine for the growth and strengthening of skeletons in stony corals, sponges and crabs; selenium for eliminating free radicals, and iron, manganese, zinc, copper, nickel, chromium, cobalt, molybdenum and vanadium for the development of important enzyme complexes. With these components and balanced in its concentration ratio, Tropic Marin® All-For-Reef creates the best care conditions with just one solution. There are no additional compounds (e.g. sodium chloride) that alter the salinity or ion balance. Complete mineral supply with only one component All essential trace elements are already included (all elements of the Tropic Marin® K+ and A- Elements) No formation of by-products (e.g. sodium chloride); the salinity and the ion balance are not changed No formation of excess carbon dioxide Suitable for aquarium stocking with soft corals, LPS, SPS, azooxanthellate filter and/or crustaceans Easy to use - suitable for both manual dosage and for dosing pumps after dissolving Tropic Marin® All-For-Reef Powder contains organic calcium salts, salts of magnesium, strontium and trace elements. 1000ml of this solution supplies the aquarium with approx. 43,000 mg of calcium, 6,000° of carbonate hardeners, 1,900 mg magnesium, 780 mg of strontium, and 34 mg of iodine as well as all other important trace elements. The 800 g dose of All-For-Reef Powder is enough for 5 litres of dosing solution, the 1600 g dose is enough for 10 litres of dosing solution. 6 level measuring spoons (approx. 160 g) All-For-Reef Powder are dissolved in 1 l of reverse osmosis water to create the liquid mineral blend. This solution has a long shelf-life and contains 43,000 mg of calcium, 6,000° of carbonate hardeners, 1,900 mg magnesium, 780 mg of strontium, and 34 mg of iodine as well as all other important trace elements. You can now start with daily doses of 5 ml of the mineral solution for every 100 l of aquarium volume. Monitoring the carbonate hardness, increase the daily dosage by 2.5 ml for every 100 l of aquarium volume every week until you reach a constant carbonate hardness level of 7 to 9 °dH. Maximum dose: 25 ml of solution per 100 l of aquarium volume daily. As soon as the mineral mixture is dissolved in the water, the solution is ready for use.
