Review on 🐟 HOTOOLME Aquarium Algae Scraper: 25.6" Stainless Steel Cleaning Razor with 10 Blades for Glass Fish Tanks by Ashley Gomez

I was frustrated with these stubborn algae that are difficult to remove in my koi tank. I was looking for a manual razor blade but found this GEM! I'm amazed I used it in my other tank which wasn't too bad and it really helped revive my cichlids. Someone mentioned that they can't use it on the rear window if it's against a wall, but I was able to. This tool is a game changer. And yes, be careful, the blade is sharp! It also comes with a set of blades and is reversible.
