Review on NEPTONION Professional Algae Scraper: 24.5’’ Aquarium Blade Cleaner 🐠 with Replaceable Blades - Ideal for Tanks Above 30 Gallons by Joyce Keesling

I have many aquariums and I feel like I've tried every possible cleaning method. This aquarium arrived in a tiny box. There are many details: two parts of the handle, a connector, a head, screws, blades and much more. I found assembly easy except for the blades. . . the instructions are in chinese, and although there are four pictures, they include the obvious, not really necessary, part, inserting the blade. After assembly I was not thrilled. The vacuum was light, flimsy, and I doubted it would do the job. I was surprised that it does a really good job cleaning glass. Even the tank in the window that grew like a jungle. . . or the one in the living room that grows hard stuff that the plastic won't peel off. Aside from the flimsy feel, another thing to look out for is the actual blade. This type of tool cannot be used on acrylic tanks. . . but it also cuts sealant on glass tanks with little difficulty.
