Reeflowers Alkaline I Natural Aquarium Minerals, 34-oz bottle

Every aquarium has a different kH consumption level. Before using the product determine the kH degree of your aquarium using an appropriate test kit. A maximum of 2 tsp (10 ml) of solution can be used per 26 US gallons (100 liters) of water at a time until the desired level is reached (10 ml of solution provides 1 dkH increase in 100 liters of water). Once the desired level is reached, optimum consumption can be determined by means of periodical tests; solution can then be added daily or weekly as required. If the daily consumption level exceeds 0,5 dkH, it is recommended that the solution is added continually via a dosing pump: 1 cap = ~ 1.2 tsp (6 ml).
