The Reef Sodium Bicarbonate 4Kg

TheReef® supplies a broad range of dry chemical salts suitable for use in freshwater and marine aquaria. These pure food or pharmaceutical grade salts require a little preparation but can be an economical alternative to commercial liquid additives. The Balling Method / 3-part method Hans-Wermer Balling in Germany and Randy Holmes-Farley in the USA independently developed similar recipes for supplementing calcium and carbonates using basic chemical salts, and subsequently extended their approaches to cover a reef aquarium's magnesium requirements as well. You can download an information leaflet on a simplified version of these methods here [pdf]. TheReef® supplies the following pure chemical salts for use with these methods: Sodium Bicarbonate (NaHCO3) Calcium Chloride dihydrate (CaCl2.2H2O) Magnesium Chloride hexahydrate (MgCl2.6H2O) Magnesium Sulphate heptahydrate (MgSO4.7H2O) Available in 1kg, 2kg and 4kg sizes only. Kalkwasser A solution of Calcium Hydroxide - often referred to by its German name of 'Kalkwasser' (Limewater) - is an economical and well established method for maintaining calcium and alkalinity levels in marine aquaria. Kalkwasser is a balanced additive that adds both calcium and carbonates in the same proportions as these ions are taken up by stony corals. TheReef® supplies the following pure chemical salts for use with this method: Calcium Hydroxide (Ca(OH)2)
