  • Seachem Safe

    Seachem Safe

    Product Description Safe™ is the complete and super-concentrated dry conditioner for both fresh and salt water. Safe™ removes chlorine, chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH. A further bonus for the reef hobbyist—Safe™ will not over-activate skimmers. Safe™ may be used during tank cycling to alleviate ammonia/nitrite toxicity. It contains a binder which renders ammonia, nitrite, and nitrate non-toxic, allowing the biofilter to more efficiently remove them. Use at start-up and whenever adding or replacing water. When transporting or quarantining fish, use Seachem StressGuard™. When adding new fish, use Stability®. Both are ideal for use with Safe™. Use 1.25 g (1/4 tsp.) for every 1,250 L (300 US gallons) as needed to reduce chlorine and chloramine or use 1.25 g (1/4 tsp.) for every 300 L (75 US gallons) for ammonia. For precise dosing, use the Seachem Digital Spoon Scale. NOTE: These directions supersede all other prior packaging. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite and nitrate in an emergency, up to 4 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.

  • Seachem Renew 100ml

    Seachem Renew 100ml

    Product Description Renew™ is ideal for use in systems where phosphate released from all activated carbons poses a problem. Renew™ is also less aggressive than carbon, making it well suited for reefs and planted aquaria. It is also beneficial for use in soft water aquaria where the pH-raising property of many carbons is not an asset. Renew™ will remove organics and particulates in the sub-micron range; it will also help control ammonia, nitrates, and phosphates. Sizes: 100 mL, 250 mL, 500 mL, 1 L, 2 L, 4 L Renew™ should be used in exactly the same manner as activated carbon. Use 250 mL for each 120–160 L (30–40 US gallons). For best results, Renew™ should be placed so as to maximize the flow of water through it. Use in a filter bag such as the Zip Bag™. Although Renew™ is clean, it is advisable to rinse before use. It lasts about the same as carbon (4–6 weeks).

  • Seachem Reef Trace 500ml

    Seachem Reef Trace 500ml

    Product Description 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 plant and invertebrate species. In general, though, these elements are important for metabolic processes and pigment formation. Addition of iron, for instance, has been shown to benefit coloring and growth for corals, anenomes, and other photosynthetic animals. 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™. Best results are obtained when both are used. Reef Trace™ is nitrate/phosphate free. Use 1 capful (5 mL) for every 80 L (20 US gallons) twice a week. When using in conjunction with Reef Plus™, dose on alternate days.

  • Seachem Reef Kalkwasser 500g

    Seachem Reef Kalkwasser 500g

    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.

  • Seachem Reef Iodide 500ml

    Seachem Reef Iodide 500ml

    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].

  • Seachem Reef Complete 500ml

    Seachem Reef Complete 500ml

    Product Description 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. 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. To prevent this you must provide calcium (Reef Complete®) and carbonates (Reef Builder™ or Reef Carbonate™). 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® is a blended product. It is not simply calcium chloride. Commercially available calcium chloride contains ammonia. Unlike other ionic calcium supplements, Reef Complete® is blended to a higher pH in order to force the ammonia to gas off into the atmosphere. In addition, Reef Complete® is more concentrated than any other liquid product on the market. Reef Complete® contains 160,000 ppm calcium. Our nearest competitor’s product is only 110,000 ppm calcium. Beginner Use 1 capful (5 mL) per 80 L (20 US gallons) twice a week. Check calcium every 2 weeks and adjust amount or frequency accordingly. Advanced Check calcium level (use Reef Status™: Calcium to measure calcium), then follow 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 tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 US gallon=3.8 L]. Notes If used with Reef Calcium™, it is not necessary to exceed 380 mg/L total calcium. Use Reef Status™: Calcium to measure calcium.

  • Seachem Reef Calcium 500ml

    Seachem Reef Calcium 500ml

    Product Description 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. 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. 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. 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 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. Sizes: 100 mL, 250 mL, 500 mL, 4 L

    Product Description Plant Pack™: Fundamentals is an excellent pack for beginning aquatic gardeners. It contains Flourish®, Flourish Iron™, Flourish Excel™. Flourish® Flourish® is a growth stimulator for aquarium plant stems and leaves. It contains a broad spectrum of essential trace elements, vitamins, and amino acids. Flourish® is rich in gluconate iron, manganese, calcium, magnesium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plants. Flourish Iron™ Flourish Iron™ is a companion product to Flourish® and Flourish Tabs™. It is a complexed ferrous (Fe+2) iron product which contains 10,000 mg/L of iron and is ideal for iron maintenance in the natural planted aquarium. Plants can utilize both ferric (Fe+3) and ferrous (Fe+2) iron, although they prefer ferrous iron when available. Flourish Excel™ Flourish Excel™ is a simple source of readily available organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be obtained via relatively simple organic compounds (such as photosynthetic intermediates). Since both processes occur simultaneously one can derive a substantial benefit with the use of Flourish Excel™ either alone or in conjunction with CO2 injection.

  • Seachem Neutral Regulator 7.1-7.6 250g

    Seachem Neutral Regulator 7.1-7.6 250g

    Product Description Neutral Regulator® adjusts pH to neutral (pH 7.0) from either a low or high pH and maintains it there. It softens water by precipitating calcium and magnesium while removing any chlorine, chloramine, and detoxifying ammonia. The use of Neutral Regulator® makes other conditioning unnecessary. To lower pH below 7.0 use Neutral Regulator® with Acid Regulator™ (or Discus Buffer®). To raise pH above 7.0 use with Alkaline Regulator™. All of these products will enhance and stabilize the freshwater aquarium environment. For further freshwater environment enhancement, use Fresh Trace™ to restore the proper level of trace elements and feed NutriDiet® Tropical Flakes for thriving, healthy freshwater community fish. Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to neutral pH. Use 5 g (1 level teaspoon) for every 40–80 L (10–20 US gallons) once or twice a month (or as necessary to maintain a pH of 7.0.) Neutral Regulator® may be be initially used daily in cases of high alkalinity until 7.0 is established. It may be added directly to the aquarium at any time. Ideally, it should be used when adding or changing water by dissolving in the replacement water. For precise dosing, use the Seachem Digital Spoon Scale.

  • Seachem Matrix Carbon

    Seachem Matrix Carbon

    Product Description MatrixCarbon™ is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. MatrixCarbon™ has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0. While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon™ has the lowest detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon™ outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use. While carbon is generally considered to be a chemical filter, that is not precisely true. It is in fact a mechanical filter as well, but it is only capable of mechanically filtering objects of molecular size. It functions through extremely small cracks and crevices, called macropores and micropores. Microporous carbons remove primarily metals and smaller ions (like trace minerals) and are best suited to air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration. The ingredients from which a carbon is manufactured determine whether it will be macro- or microporous. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons. MatrixCarbon™ is a bituminous coal-based, macroporous carbon. It is the only spherical carbon on the market, allowing for maximum water flow. It is sized to allow full penetration by water, but not small enough to escape filter bags. All carbons contain phosphate. However, that phosphate DOES NOT come from washing the carbon with phosphoric acid. Most carbons are washed with sulfuric acid. The phosphate is contained in the ash from the carbon source. The main purpose of acid-washing is to remove ash. Because of MatrixCarbon’s™ hydrodynamic properties, more ash is washed from our carbon than any other. Therefore, it has the lowest leachable phosphate on the market.
