CrystalClear Blue PondTint turns your pond an alluring shade of blue to help photosynthesis from occurring within your pond. This will help keep algae from forming, provide safety for fish from predators and will help keep the water cooler on the hot summer days. CrystalClear Blue PondTint is a mild dye that is not overpowering, so that you will still be able to see your fish. It is designed to function more like a car window tint instead of a complete cover.
