Crystal Clear makes pond water crystal clear quickly and easily.Whether for newly installed or existing ponds, Crystal Clear eliminates any form of turbidity in the water through a completely harmless reaction. Some of this clumping sinks to the bottom and some floats on the water, making the water clear again. To achieve optimum results, it is important that the dirt is skimmed off. Please note, however, that Crystal Clear removes the turbidity, but not the cause of the problem. To keep the water clear for longer, we recommend introducing oxygenating plants such as hornwort, waterweed and pondweed as well as floating plants such as frogbit, duckweed and Azolla moss fern. With Crystal Clear, you can make pond water crystal clear quickly and easily and achieve optimum results!
