ReBorn is a coarse aragonite media for calcium reactors.Composed of fossil skeletons of reef building corals sustainably harvested from pristine sites in the Western Pacific. When used in a calcium reactor where it is dissolved with CO2, ReBorn not only replenishes calcium and carbonate alkalinity, it also replenishes strontium and trace elements in the same proportions they are used by corals to build their skeletons. In this way ReBorn replaces exactly what corals need to grow. Unlike many other calcium reactor media, the coarse size of ReBorn allows for unrestricted water flow and easy diffusion of carbon dioxide, for maximum efficiency and easy maintenance of the calcium reactor. The naturally porous structure promotes carbon dioxide penetration assuring a uniform dissolution rate.ReBorn dissolves completely and will not turn to mush! These features combined with it's very low phosphate and silicate content mean that ReBorn is the ideal media to use for promoting the growth of live corals, clams, calcareous algae, and other calcifying creatures in a reef aquarium.

MarinePure Bio Filter Media Spheres - 1 Gallon
MarinePure Bio Filter Media Spheres - 1 Gallon Overview MarinePure is the perfect place for beneficial bacteria to flourish in order to remove harmful fish wastes. It will eliminate ammonia and nitrites and lower nitrates. MarinePure's bio-media is the most technically advanced bio-media available today. Features A Combination of vast surface area and open/interconnected pores allow a thin bio-film to develop. This thin film allows bacteria to flourish because necessary nutrients are immediately available. With the open pores, old dead bio-film is easily flushed from the media and will not plug the media. Water flows through the media, not around as with other denser medias, thus utilizing the most surface area for beneficial bacterial growth. Benefits Better value due to high performance Reduced tank maintenance Allows for higher fish loads Can use a smaller filtration footprint More consistent water chemistry Spheres are Easy to shape MarinePure is inert and will not harm aquarium inhabitants. Application Used in tank or in sumpsUsed in canister and DIY filtersUsed in trickle, shower, or waterfall filtersUsed in hang on back filtersSpecifications Contents: 1 Gallon (3.8 liters) of 1.5" Spheres Surface Area per Sphere: 22 sq. meters (240 sq. ft) How to Use MarinePure Filter Media Rinse new media under tap water to remove any loose particles.
