Matala 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.
What is the difference between an ultraviolet sterilizer and an ultraviolet clarifier? Actually, there is not a difference in the units themselves, the difference is in the ratings provided for the appropriate pond size and flow rate. By following UV sterilizer ratings the pond should have clear water despite most other conditions and the UV will also be more effective against controlling microscopic pathogens. A UV clarifier rating typically means that you may not have crystal clear water all the way to the bottom. It also assumes that the pond has good plant coverage (greater than 50%) and adequate biological filtration. When following UV clarifier ratings it is a good idea to oversize the UV to help ensure cleaner water.
