1.UV Sterilization is a safe and natural method to reduce waterborne pathogens and algae the causes “Green Water”.
2.UV is as natural as sunlight. Unlike chemical treatments that can potentially harm the fish, beneficial bacteria, and plants
in your aquarium or pond, UV does not leave any residuals in the water and therefore cannot harm fish and plants.
3.A UV sterilizer works in harmony with other essential filters by eliminating nuisance green water caused by waterborne
algae that can easily create problems and ultimately reduce filter efficiency.
4.Drain valve in the bottom can keep the sewage from remaining in the UV pipes when the UV sterilizer is free.That is a new design,and makes a good effect.
