JBL Clearol Water Clarifier for Freshwater, 100ml, Blue

Highlights: Water conditioner for crystal-clear water. Creates crystal-clear water in freshwater aquariums and turtle tanks. Eliminates micro-fine cloudiness, which normally can't be collected from the filter, such as smallest floating particles (white cloudiness), water bloom (green cloudiness) and bacterial cloudiness. Turbidity sinks to the bottom and can be siphoned or collected from the filter. Tip: clean filter more frequently to remove solid turbidity. Use with pH levels over 6 and KH levels over 5° dKH.
