Easy to use combination liquid calcium supplement for marine aquariumsProvides vital calcium, magnesium, and strontium for healthy coral growthRestores and maintains calcium to levels found in natural seawaterComprehensive, inorganic supplement designed to safely restore calcium, strontium, and magnesium in reef and saltwater aquariums alike. Concentrated optimized blend of ionic calcium replenishes and maintains calcium to levels found in natural seawater without affecting pH. Also contains magnesium and strontium in proper proportions for convenient one-step supplementation to ensure healthy coral growth. Use alone or in conjunction with Reef Calcium for optimum results. 1 ml delivers 160 mg of calcium. 250 ml treats approximately 1,000 gallons.Please click on "More Information" for directions for use.

Restores and maintains alkalinity in reef aquariums Prevents calcium and carbonate deficiencies in saltwater aquariums Provides essential levels of alkalinity for coral growth and health Concentrated liquid blend of carbonate and bicarbonate salts designed to restore and maintain alkalinity in reef aquariums. Reef Carbonate allows proper coral growth and health by providing and maintaining alkalinity and by preventing calcium and carbonate deficiencies in reef systems. Will not deplete calcium, magnesium, or strontium, all of which tend to precipitate with increasing alkalinity. 500 ml bottle treats 2,000 gallons.Please click on "More Information" for usage instructions, hints and precautions.

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.

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.

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.
