Will a UV sterilizer help clear green or hazy water in my aquarium?
Yes, UV sterilizers target free-floating algae and microorganisms that contribute to green or hazy water, which can improve overall clarity. For best results, use a unit that matches your tank size and flow rate so enough water passes the light regularly.
What is the difference between an aquarium UV sterilizer and a pond clarifier, and can a pond unit be used indoors?
Pond clarifiers are made for ponds and are labeled for pond use and fish types like koi, but aquarium UV sterilizers are rated for freshwater or saltwater tanks and list the right tank sizes. For indoor aquariums, choose a model labeled for aquariums and match its capacity and flow guidance to your setup.
