Clears cloudy white water. Clear-UP is a 100% natural water clarifier, consisting of beneficial bacteria, with the ability to "floc" small particles from the aquarium water. The result is clear water without the use of harmful chemicals contained in other water clarifiers such as alum (which contains aluminum) and polyacrylamide (a potentially toxic chemical).
Directions: Shake well before using.
Dosing: Add 5 ml (1/2 capful) per 10 gallons of aquarium water.
For best results, temporarily turn the filter off, add Clear-UP over the entire aquarium water surface, wait 10-15 minutes for flocs to form, and then turn the filter back on.
In extreme cases, aquarium water may not clear up for 24 hours. You may safely use Clear-UP repeatedly.
