Small particles that swim freely in the water cause turbidity. ReeFlowers AquaClear gathers these small particles together causing them to take on a flake form enabling them to be easily removed by filtering equipment. The solution not only helps to keep water clear but can also prevent the formation of algae. The effects of the solution are visible immediately and continue to work over an 8-hour period to create a crystal clear environment. The solution has no effect on pH levels and can be used in both freshwater and marine aquariums. It is recommended that 5ml is added for every 100 liters of water in an area of flowing water. Do not exceed the recommended dose and wait at least 3 days between treatments.
