Quickly Clarify your Freshwater Aquarium's Water with Accu-Clear Helps clear cloudy or green water Will not harm fish or live plants Assists filtration by clumping tiny particles together API Accu-Clear water clarifier quickly clarifies cloudy water in your aquarium, eliminating haze to make your water crystal clear. Accu-Clear clumps tiny floating particles together, forming large particles to be more easily removed by your aquarium filter. Safe for use with all freshwater fish and plants. Accu-Clear can also help to clear the cloudiness caused by bacterial blooms but does not address the underlying cause. As a result, the cloudiness will come back quickly unless the main cause of bacterial blooms is treated. Directions: Add 1 ml per 10 gallons of aquarium water. The water will clear within several hours. If a second dose is necessary, wait 24 hours. A third consecutive dose is not recommended, however, Accu-Clear can be dosed on a once weekly basis as part of your routine aquarium maintenance.
