    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.

    Pearl Beach™ is an all natural aragonite substrate for all types of marine, reef and tropical aquaria. Its chemical composition will assist in stabilizing calcium and alkalinity while preventing large pH declines. Unlike competing “wet” gravels, Pearl Beach™ is sold dry: this bag contains 35% more gravel than a bag of wet gravel of equal weight. These “wet” gravels are marketed to give one the impression that they contain living, microscopic animals when in fact they only contain common bacteria. Dry or wet, there are bacteria on every substrate. If one is concerned with shortening the aquarium cycle time for a new system, then the use of a product designed for that particular purpose would be more appropriate (such as Seachem’s Stability®).

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Cichlid Lake Salt™ is a chemically sound blend of salts designed to replicate the natural environment of Rift Lake African Cichlids. It contains all physiologically essential elements such as magnesium, calcium, sodium, potassium, and includes trace components such as iron, aluminum, and iodide. Although the major Rift Lakes contain basically the same mineral salts, they do so in greatly differing concentrations. Cichlid Lake Salt™ is formulated so that dosages vary depending on the lake of origin and need only be added when setting up an aquarium or with water changes. Many competing products are little more than combinations of Epsom salt and bicarbonate of soda. This will not provide a complete replication of the mineral salts that are contained in the lakes of Africa, in particular calcium and potassium. Seachem’s Tanganyika Buffer™ (pH 9.0–9.4) and Malawi/Victoria Buffer™ (pH 7.8–8.4) should be used to adjust carbonate hardness and pH.

  • DeNitrate DeNitrate

    Seachem DeNitrate

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    DeNitrate is an economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrification within the first few millimeters of depth and anaerobic denitrification at the core. The material has a high surface area and supports a high density of bacteria. Although DeNitrate has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic. “Live”rocks or reef rocks remove nitrate by anaerobic denitrification. DeNitrate removes nitrate by the same process. Efficiency is magnified several folds by forcing the water to filter through the porous DeNitrate. As with reef rock, anaerobic conditions are achieved by the porosity and the depletion of oxygen by the aerobic process at the surface. Excessive flow rates should, therefore, be avoided, as they may impede development of an adequate anaerobic environment to support denitrifying bacteria. DeNitrate is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters. At high flow rates (greater than 100 US gallons per hour), it will function solely as an aerobic filter. At slow flow rates (less than 50 US gallons per hour), it will function as both an aerobic filter and an anaerobic denitrifying filter.

  • Flourish Iron Flourish Iron

    Seachem Flourish Iron

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Iron is immobile in plants. This means that plants cannot divert iron from older leaves to new ones. Therefore, deficiency symptoms appear first on new or young leaves. Because plants use iron to produce chlorophyll, a lack of iron results in chlorosis, or yellowing, of the younger leaves. Stems may also appear short and slender. If the deficiency is severe and prolonged, each new leaf emerges lighter in color than the preceding leaf. When choosing an iron supplement, it is important to know the distinction between the two forms of iron. The iron will be in one of two oxidation states: ferrous having a +2 charge, or ferric having a +3 charge. Ferrous iron, the preferred iron form and is soluble in water at any pH. Ferric iron, however, is only soluble below a pH of around 5.5; but if the pH is higher than 5.5, which more than likely it will be in a planted aquarium, the ferric iron will become insoluble and precipitate, settling in the root zone. Once this occurs, foliar absorbtion becomes impossible. To overcome this precipitation, competing products employ a chelate of ferric iron: iron-EDTA. While this does keep it soluble, it has a couple of drawbacks with respect to foliar uptake of iron. (1) Iron-EDTA bonding is very strong, thus very little of the iron will be available to the plants over a given time frame and (2) Physiological energy must be expended by the plant in order to extract the ferric iron from EDTA-iron and then convert (reduce) it to the ferrous form. Our approach is different in that we use a complex (not chelate) of ferrous iron in Flourish Iron™. Flourish Iron™ is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a benefit from Flourish Iron™ because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it. Despite what other manufacturers may intimate, gluconate is not harmful to plants or fish. In fact, ferrous gluconate is better suited to foliar feeding than is iron-EDTA owing to the relatively weaker iron-gluconate bonding vs. iron-EDTA bonding. In addition, ferrous gluconate has the added bonus of being a source of carbon.

    Seachem Reef Potassium

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Potassium is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. In systems supported with nitrogen and phosphorus supplementation, potassium utilization rates may be increased. Supplementing with Reef Potassium provides a targeted means of increasing potassium concentrations effectively without also adding phosphate or dissolved organics. In many reef aquariums, potassium supplementation can enhance coral and macroalgae growth and color – particularly red and pink colors in corals. Ideal potassium levels will vary but generally range from 380 - 400 mg/L potassium. Reef Potassium contains 10% elemental potassium. Use Reef Nitrogen and Reef Phosphorus to maintain optimal nitrogen and phosphorus levels.

    Seachem Reef Nitrogen

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Nitrogen is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. Research suggests a tightly closed nitrogen cycle on reefs where concentrations are higher in micro-zones near the corals (Radecker 2015, Wiedenmann, 2023) than in the surrounding water.  It is important to maintain nitrogen levels along with phosphorus levels in order to allow for optimal growth and coloration of corals and macroalgae. Supplementing with inorganic nitrogen provides a targeted means of increasing nitrogen without also adding phosphate or dissolved organics. A typical nitrate test will show all forms of nitrogen being added by Reef Nitrogen.  Reef Nitrogen is easily dosed manually as well. Ideal nitrogen levels will vary but generally range from 1 – 2 mg/L (4.4 – 8.9 mg/L nitrate). Use Seachem’s Reef Phosphorus to achieve a balance of nitrogen to phosphorus levels for optimal results.
