  • Flourish Nitrogen Flourish Nitrogen

    Seachem Flourish Nitrogen

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Nitrogen is one of the main three macro nutrients (nitrogen, phosphorus, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the plant–preferred ammonium form. However, no free ammonia is released because the ammonium in Flourish Nitrogen™ is complexed and unavailable until utilized by the plants. Ammonium becomes available after conversion of urea (carbamide). Flourish Nitrogen™ also provides nitrate for those plants that can readily utilize nitrate as well. For maximum benefit, use with Flourish Phosphorus™ and Flourish Potassium™. Flourish Nitrogen™ is safe for invertebrates such as shrimp.

  • Reef Nitrogen

    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.

  • Axolotl Conditioner

    Seachem Axolotl Conditioner

    4 in stock Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Seachem Axolotl Conditioner is a concentrated aquarium water conditioner that makes tap water safe for Axolotls by removing chlorine, chloramine and detoxifying ammonia. It converts ammonia, which is highly toxic to Axolotls, into a safe, non-toxic form that is readily removed by the tank’s biofilter. Axolotl Conditioner also detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them making it effective during tank cycling to alleviate ammonia/nitrite toxicity. Additionally, it detoxifies any heavy metals found in the tap water at typical concentration levels. Axolotl Conditioner is non-acidic and will not impact ph. Use Seachem Axolotl Buffer for safe and effective pH management. Axolotls can produce high levels of ammonia so it is very important to cycle your aquarium with beneficial bacteria such as Seachem Stability to safely establish and maintain efficient biofiltration.

    Iron is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. Iron supplementation can enhance coral and macroalgae growth and color – particularly yellow and green colors in corals. In systems supported with nitrogen and phosphorous supplementation, iron utilization rates may be increased as iron assists in assimilation of nitrogen.   Iron supplementation can enhance coral and macroalgae growth and color – particularly yellow and green colors in corals. Supplementing with Reef Iron™ provides a safe means of increasing iron concentrations. Reef Iron™ is ideally suited for use with an aquavitro sentia dose doser to maintain iron at a consistent concentration based on your aquarium's unique demand but is easily dosed manually as well. Ideal iron levels will vary but natural seawater generally ranges from 0.003–0.01 mg/L iron. Reef aquariums are often kept at higher levels for optimal coloration and growth. For optimal macro algae growth, many find 0.05–0.1 mg/L to be beneficial. Use Reef Nitrogen™, Reef Phosphorus™ and Reef Potassium™ to maintain optimal nitrogen, phosphorus and potassium levels.

  • Seachem Catappa Leaves Med

    Seachem Seachem Catappa Leaves Med

    4 in stock Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Catappa leaves coming from Indian Almond Trees (Terminalia catappa) help to replicate natural environments for Bettas, shrimp and other aquarium inhabitants. When added to an aquarium, they release tannins and other organic compounds which aid in maintaining lower pH and gently tinting water. These conditions mimic habitats with acidic water and abundant leaf litter. As catappa leaves decay, beneficial micro-organisms grow on the leaf surface, creating a natural source of food for shrimp, snails, and newly-hatched fish. Add 1-2 leaves per 20 liters (5 US gallons). Remove and replace every month or as desired. Catappa leaves may float initially but will sink after 2 - 3 days. To make an extract, boil three grams (approx. two-and-a-half leaves) in 1 liter (1 US quart) of water for ten minutes or until desired color is attained. Let extract cool to aquarium temperature and pour directly into the tank or mix with prepared water for water changes. When first using extract, add gradually over a 2 to 3 days and monitor to ensure pH stays within suitable range for tank inhabitants. Chemical filtration media such as activated carbon can remove compounds provided by Catappa leaves.

    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.
