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

I have purchased three Green Killing Machines. One of them is my 72 gallon tank, I had an algal bloom problem, it went away within a few days. The other two I put in my 220 gallon tank were fine, but after running the machines for about a week the fish were much cleaner and more pleasing to look at. These things don't come cheap, but after investing a lot of money into customization, why not make the tank as good as possible to be worth the money?
