Clarifi-FW - Advanced Freshwater Clarifier (500 mL)

Advanced Clarifier for all Freshwater and Planted Aquariums

• Helps eliminate cloudy water
• Improves flocculation and water clarity
• Enables better particulate removal during mechanical filtration
• Safe for all freshwater fish, plants, and invertebrates

Cloudy water in an aquarium is usually caused by different types of tiny particles floating in the water from too many nutrients, burrowing activities of fish and invertebrates, or strong water flow stirring up sediment. Clarifī-FW helps to clear cloudy water by using electrical charges to bind these particles together so that the resulting larger and heavier particles can be more easily filtered out or removed by siphoning. 

Instructions & Guidelines

Do not use in marine aquaria; instead, use Clarifī-SW. Extensive research in our facility has revealed that maximum performance in freshwater and saltwater aquaria is achieved with different active ingredients rather than with one ingredient that is compatible in both types of aquaria. The active ingredients in Clarifī-FW are incompatible with marine aquaria.

Shake bottle prior to use. Do not "free pour" into aquarium, which may result in excessive, persistent cloudiness. Flocculation of cloudiness due to blooms of microalgae may result in a depressed pH as the production of oxygen and uptake of carbon dioxide decrease; therefore, ensure that alkalinity measures at least 2 dKH prior to use and do not dose after display lights have turned off for the day (this is the period of time in which pH levels naturally decrease slightly, and an additional decrease in pH due to the afore-mentioned process may be stressful to aquarium inhabitants).

Replace or rinse mechanical filtration material prior to use; when filtration media nears capacity (signified by a significant decrease in water flow through the exhaust of the power filter, or pooling of water above horizontally-situated filter pad material), replace or rinse it, and repeat as necessary.

Recommended dosage is ~1-ml of Clarifī-FW per 10 US-gallons (37.9 L). Dilute up to 10-ml of Clarifī-FW per 8 fl-oz. or 250-ml of purified water and stir to disperse; gradually pour the resultant solution into the aquarium in an area of rapid water flow. Allow at least 12-hours for flocculation process to complete; re-apply in 24-hours if necessary. Maximum recommended usage is twice per 5 day period. Reoccurrence of cloudy water after Clarifī-FW has been employed to satisfactorily clarify water is an indication that issues referred to in Technical Background (opposite panel) may need to be addressed. The long-term successful care of aquaria relies upon the employment of sound husbandry principles.

Clarifī-FW is not formulated to remedy water discoloration (e.g. "yellow" tint) caused by dissolved organic material; instead, employ activated carbon (e.g. Brightwell Aquatics Carbonīt-P) and/or macroadsorptive resin (e.g. Brightwell Aquatics OrganītR) for this purpose.

Caution: Do not use in marine aquaria; do not use at night. Keep out of reach of children. Not for human consumption.
