Instructions: 100mL will raise 25 gal of water by 3dKH. Shake well before use. Measure the desired amount of Triton CO3 and slowly add the solution to a high-flow area of your aquarium. Adding the solution too quickly can cause precipitation. It is also very important to monitor the pH of the aquarium when CO3 is added. We do not recommend increasing your alkalinity by more than 1.4 dKH per day.
