Review on 🐠 GKM24W Internal UV Aquarium Filter for Tanks up to 120 Gallons, Black by Patty Yenbamroong

This UV filter made my pea colored aquarium water crystal clear in just three days! It works, so buy it! UPDATE: UV lamp failed after 5 days! Sent it back to Revain and asked for a replacement. Disappointed, it worked so well until it stopped working. Hopefully the replacement will last longer. UPDATE: The replacement block works fine. That thing really makes the water crystal clear. Rating changed to 5 stars.
