Matala EZClear UV Pond Clarifiers



Matala EZClear UV-C Clarifiers are designed for Koi ponds and water gardens to help suppress blooms of suspended green algae, harmful bacteria, parasites, fungi, protozoan and viruses.

Even in a balanced pond ecosystem, sudden blooms of such organisms can occur due to abnormal changes of weather, fish feeding behavior, mineral nutrient levels, etc. These blooms may result in green water, lethal oxygen levels or weakened health conditions for fish and aquatic plants.

The Matala EZClear UV Clarifiers can be used as a standalone UV added to an existing filter system. The 16 Watt drops into the BioSteps filter easily. The 25, 40 and 75 Watt UVC do not fit the Biosteps filter. These are standalone units which can be installed on your pond system with the proper size pump.
