Pur Kalkwasser™
maintains calcium and alkalinity

Pur Kalkwasser™ is pure calcium hydroxide powder that is used to prepare kalkwasser solutions that will help to maintain high calcium concentration and alkalinity or carbonate hardness (KH) in aquariums. A wide variety of invertebrates in reef aquariums including soft and hard corals, mollusks, crustaceans, clams and calcareous algae absorb calcium and carbonate from the water for protection, body support (skeletons) and calcification.
Pro Series Buffer 8.3™
raises and maintains pH to 8.3

Pro Series Buffer 8.3™ is a solution that contains a balanced blend of bicarbonate, carbonate and borate salts. It is designed to adjust the pH between 8.0 to 8.3 and raise alkalinity or carbonate hardness (KH). Alkalinity is important for maintaining a high pH. Pro Series Buffer 8.3™ is also essential for coral growth when used with our calcium additives. A wide variety of invertebrates in reef aquarium including corals, mollusks and algae absorb calcium and carbonate from the water for protection, body support and calcification.
Pro Series SeaBalance ™
two parts, A & B

Pro Series SeaBalance™ is a highly concentrated two-part calcium and alkalinity buffer maintenance system that replenishes calcium and alkalinity with the correct ratio of ions to the composition of Natural Seawater. SeaBalance™ also includes magnesium and strontium in the amounts proportionate to typical utilization ratios. Without high concentrations of magnesium, all the calcium would combine with carbonates and precipitate out of the aquariums. Alkalinity is primarily the concentration of calcium, magnesium, carbonate and bicarbonate, which helps maintain a high pH and is essential for coral growth.
