"I love this scraper."

This set really save me lots of time when I clean my aquarium. I have no idea how this would hold up to much larger tanks. The one hassle to this scraper is that mounting the blade can be very tricky. And i love that the handle is so long, I have a very deep tank. If you hate cleaning and scrubbing your tank this thing is for you. That has an impact on how well this brush works. Dont have to get wet, its very long, about 33 inches at maximum extension.

"Very easy to use."

Guess how I learned that mistake lol. Happy with the set and all the different interchangeable attachments. The only issue is there is no blade cover provided for storage. I would have gone to the next size up to get the extra pressure on the inside glass. How can a pandemic cause algae you ask. It works awesome and does everything I wanted it too and more. I don't have that worry with this scraper.

I hand no issues with it scratching the glass. I bought this size algae scrubber because I have a 13. I have a fairly deep sand bed in my 90 gallon reef tank. The magnet is stronger and best of all it finally floats to the surface. I have a 55 gallon tank and this does a very good job removing algae from the glass.

"This works great."

But for the price I paid, I don't mind water running down my arm one bit. Guess how I learned that mistake lol. The magnet is stronger and best of all it finally floats to the surface. This scrapper will trap some of it making it easier to get out of the tank. Nano magnet is a little weak on 6 mm WaterBox, but still works fine. I placed it on the rod and cleaned the corners of my tank. I know alot of people feel this is junk.

"Overall a great scraper."

This scraper is for an acrylic aquarium. For stubborn spots, you may need to scrub a bit harder. Cuts through built up algea in hard to reach places with no problems! Like the old kids toy dinosaur head that closes mouth by squeezing. But since no directions come, I thought I might mention it. One or two passes and glass was spotless. It works great for my tank, you may want to get a bigger pad for larger tanks.
