Matala UV-C Clarifiers are designed for Koi ponds and water gardens to help eliminate green water algae, harmful bacteria, parasites, fungi, protozoan and viruses. Even in a balanced pond ecosystem, sudden changes in water can occur due to abnormal changes of weather, fish feeding behavior, mineral nutrient levels, etc. These changes may result in green water, lethal oxygen levels or weakened health conditions for fish and aquatic plants.

Although designed to install in Matala Biosteps Gravity Discharge Filter, these versatile UV units may be used independently in a wide range of other applications that would benefit from UV clarification. Note: Second image show the UV installed in the back end of a Matala UV-C 18 Watt.

Note: Pump selection is very important for the UV clarifier to operate well; if too powerful a water pump is used, it could damage the unit. This applies to any model or brand of UV clarifier from any manufacturer.
