Concentrated formula for magnesium supplementation in marine aquariumsRestore depleted levels of magnesium for optimal aquarium pH and calciumContains no ammonia, a common contaminant in liquid magnesium supplementsSeachem Reef Advantage Magnesium ia a concentrated blend of magnesium, chloride and sulfate salt designed to restore depleted levels of magnesium with minimal impact on the ionic ratios found in natural seawater. Unlike other liquid magnesium supplements, Reef Advantage Magnesium contains no ammonia 600 grams treats 2,500 gallons.Please click on "More Information" for directions for use.

Concentrated, powdered strontium for heavily-stocked reef aquariums Raises strontium levels in saltwater aquariums to natural seawater levels Stimulates vigorous coral growth in marine aquariums Reef Advantage Strontium restores marine tank strontium levels to the levels found naturally in seawater. This concentrated, dry saltwater supplement replaces the strontium depleted by filtration and heavy coral stocking. Helps replicate a more natural environment for your saltwater tank inhabitants and maintains optimum water quality. Ionically-balanced, no pre-dissolving necessary. 1 kg bottle treats 8,000 gallons.Please click on More Information for usage directions.

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.

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.
