Concentrated formula helps maintain calcium level in reef aquariumsAccelerates coral growth by providing biologically available calciumReef Calcium simplifies reef aquarium care and coral supplementationReef Calcium is specifically designed to supplement the reef aquarium with readily bio-available calcium. It promotes the growth of captive corals without the usual problems of chalk formation and depleted alkalinity. Reef Calcium is a concentrated (50,000 mg/L) biologically available polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Delivers 175 times more calcium than Kalkwasser. 250 ml treats up to 1,000 gallons.Please click on "More Information" for directions for use.

Natural Reef Calcium

Raises and maintains carbonate alkalinity (KH) without impacting pH. Supplies bioactive calcium, magnesium, and some trace elements for corals. Contains time-release ingredients, including chelating agents, to make essential elements biologically available. To control pH and alkalinity, use Marine Buffer, but to promote active growth of corals, use Reef Builder alone, or with Marine Buffer. 500 grams treats 8,000 gallons of saltwater.

Natural invertebrate food contains twelve strains of live marine microbesSimply dissolve in aquarium water for approximately 30 minutes to hatchReplicates marine snow for corals, live rock, sponges, clams, and moreFeed your marine reef aquarium with live plankton. Unique invertebrate food contains twelve strains of marine microbes that hatch in your aquarium to replicate true marine snow. Dry packed in their encysted spore state, these natural, selectively bred, micron-sized bacterial and fungal organisms nourish your soft and stony corals, live rock, sponges, clams, scallops, and other invertebrates. Plus, any uneaten microbes colonize in the substrate or biofilter to help eliminate phosphorus, balance nitrogen levels, and clean your aquarium. Simply dissolve in aquarium water for thirty minutes to hatch. Convenient, 3 oz resealable bag contains over 100 billion microbes per ounce - enough to feed a 100 gallon system over 50 times.Please click on "More Information" for use and storage instructions.

Reef buffer for convenient aquarium pH maintenanceUse Reef Buffer to safely raise the pH of your reef systemRaises pH and carbonate alkalinity to help simplify reef care Reef Buffer is primarily intended for use in a reef system where the maintenance of a pH of 8.3 is often difficult. When used as directed, Reef Buffer will raise the pH to desired levels. With this easy-to-use formula, there is no fear of accidentally over-correcting the pH to a dangerous level. Reef Buffer, a blended product, also raises carbonate alkalinity. Seachem Reef Builder should be used to raise alkalinity when pH is not a problem. 500 grams treats 4,000 gallons.Please click on "More Information" for directions for use.
