Reborn for ALK and CAL and Remag for MAG.
ReBorn is composed of the fossil sheletal remains of reef building corals sustainably harvest from prostone sites in the Western Pacific Ocean. 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 its 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.
For Magnesium you use, ReMag with ReBorn at a ratio of 1 part ReMag to 9 parts ReBorn to maintain the calcium, magnesium, and alkalinity levels in your reef aquarium water.ReMag is composed of extremely pure and soluble granules rich in magnesium carbonate. When used in a calcium reactor, ReMag gradually replenishes magnesium and carbonate alkalinity, perfect for maintaining the magnesium concentration and alkalinity in a reef aquarium.
Directions: Rinse ReMag briefly in tap water. Add ReMag to a calcium reactor at a ratio of 10% ReMag by volume to 90% ReBorn (or other aragonite media for calcium reactors) to replenish the calcium, magnesium, strontium and carbonate alkalinity that corals and coralline algae utilize to form their skeletons. Used as directed, ReMag easily maintains the ideal magnesium concentration of 1280 - 1300 mg/l in marine aquariums at a salinity of 1.025 - 1.026. If the magnesium concentration is lower than ideal, increase it first by using Two Little Fishies Magnesium Concentrate or Magnesium Pronto. After achieving a level of about 1300 mg/l, use ReMag in a calcium reactor to maintain the concentration. The coarse size of ReMag (5 - 10 mm) allows for unrestricted water flow and easy diffusion of carbon dioxide, for maximum efficiency and easy maintenance of the reactor. ReMag is soluble at a pH of 6.5. Even at typical aquarium pH values it is slightly soluble, so ReMag can be used in a sandbed to help maintain the magnesium level in the water. ReMag does not add chloride or sulfate ions that disturb the ionic balance of the water. Top off the reactor with more ReMag as needed. If ReMag does not maintain the magnesium concentration, do not reduce the pH inside the calcium reactor. Simply increase the ratio of ReMag:Reborn, but do not exceed 25% ReMag by volume as it could raise the alkalinity too high.
Never ever more dosing on ALK, CAL and MAG.
Placed my order at FJW as Dennis will carry this as a pack together.
