Review on 🐠 Aquarium Clean Light: 3W Mini UVC Light with Timer for Green Algae Clearing & Water Purification - Submersible & Waterproof Lamp for Fish Tanks, Ponds, Pools, and Home Cleaning by Katrina Coniglio

This little UV light made my aquarium crystal clear to see back to back (48" long tank) and surprisingly even after 10 days of installation 3 hours a day (it has its own timer which you can set as needed, 3 hours, 6 hours etc.) All the GSAs that were on the side of my tank are starting to disappear, this is a must if you are a serious fish farmer to have CC water hob, sump, etc.
