Matala EZClear UV Pond Clarifiers

Sale price $144.00 Regular price $176.00


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 stand-alone 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 a stand-alone unit which can be installed on your pond system with the proper size pump. The 25w, 40w and 75w are supplied with a clear adapter which allows you to connect directly to rigid 1.5" Sch 40 PVC pipe. All size units come with universal barb connectors allowing you to connect to 3/4", 1", 1.25" or 1.5" size flexible kink free or vinyl tubing .

Matala 25w UVClarifier

We have historically used a UV clarifier to help with our pond water quality. Over the winter, a rodent enjoyed chewing on the power chords to our pump and UV units. Most expensive critter ever. Was happy to find a new unit from Play It Koi that integrated quickly and easily into our current set up. Delivery was quick and we’re back up and running. Thank you!
