Distinguish freshwater remineralisation, hardness adjustment, freshwater trace elements and marine supplements. Base the selection and dosage on measured water values.
Choose minerals and trace elements for the measured requirement
Mineral and trace-element products in this category serve different purposes in freshwater and marine aquariums. The range includes products for remineralising reverse-osmosis water, raising hardness, supplementing freshwater trace elements and maintaining selected marine-water parameters.
Choose a product only after identifying the application and relevant water values. Discus minerals, mineral salts, freshwater trace elements and marine preparations are not interchangeable. Check whether the product affects general hardness, carbonate hardness or particular mineral and trace-element levels.
Calculate the dosage from the actual water volume and follow the product instructions. Make changes gradually, measure the affected parameters and avoid combining several mineral products without accounting for their total effect. Stable, appropriate values are more important than adding supplements routinely.
