Seachem® Reef Kalkwasser™ 250g

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.

Seachem® Reef Phytoplankton™ 250 mL

Reef Phytoplankton™ is a concentrated blend of green and brown marine phytoplankton designed to provide the essential fatty acids, proteins, vitamins, amino acids, with biological carotenoids for invertebrate diet. Size ranges from 1-20 μm to feed a broad range of tropical marine aquarium filter feeders and invertebrates.

Reef Phytoplankton™ contains a natural source of carotenoids which provides essential proteins as well as a more bioavailable source of pigmentation when compared to other natural sources and synthetic pigments. Carotenoids provide the extra benefit of antioxidant activity.

In addition, Reef Phytoplankton™ is enhanced to increase the bioavailability of important nutrients such as proteins, lipids, B vitamins, and other organic pigments, thus, corals expend less energy to derive the nutritional benefit.

It is blended to contain the proper ratio of fatty acids, carbohydrates, and proteins. Blending phytoplankton yields better nutritional value. Studies * show increased consumption of phytoplankton in filter feeders when using mixed cultures versus a single culture of phytoplankton.

Seachem® Reef Plus™ 250 mL

Reef Plus™ is a full spectrum reef supplement containing trace elements, vitamins, and amino acids demonstrated to have a positive impact on the growth of corals and other desirable reef creatures. Reef Plus™ is formulated to provide nutrients available from natural tropical reef waters. Contains vitamin B12, vitamin C, thiamine, inositol, choline, iodide, and other essential constituents. Reef Plus™ is nitrate/phosphate free.

Other manufacturers’ vitamin supplements are incomplete, containing only vitamins and trace minerals. Reef Plus™ contains necessary amino acids in addition to a full complement of trace minerals and high amounts of vitamin C and B complex vitamins. It is so concentrated that it can be effectively used as a food soak for frozen fish foods.

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, anemones, and other photosynthetic animals.

Seachem® Reef Reactor™ Lg 2 L

Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It has a grain size of approximately 1-3 cm. (Reef Reactor™ Md is 0.5 – 1 cm). It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material. With high levels of both calcium and magnesium, it offers an excellent means of balanced supplementation for rapid growth and propagation of corals and calcareous animals in reef aquaria. It possesses the highest level of soluble potassium of all competing brands while exhibiting the lowest levels of both aluminum and phosphorus.

Seachem® Reef Zooplankton™ 250 mL

Reef Zooplankton™ is a concentrated blend of marine zooplankton designed to provide the essential fatty acids, proteins, vitamins, amino acids, with biological carotenoids for coral growth. The particle size range is 12.5-500 μm to feed a broad range of marine aquarium inhabitants.

Reef Zooplankton™ contains a natural source of carotenoids which provides essential proteins as well as a more bioavailable source of pigmentation when compared to other natural sources and synthetic pigments. Carotenoids provide the extra benefit of antioxidant activity.

In addition, Reef Zooplankton™ is enhanced to increase the bioavailability of important nutrients such as proteins, lipids, B vitamins, and other organic pigments, thus, corals expend less energy to derive the nutritional benefit.
