Review on Efficient Cleaning with Kent Marine Pro-Scraper: 24-Inch Scraper for Aquariums by Leslie Whitehorn

I like this a lot more than magnetic scrapers. Works very well. I used metal to get rid of the calcium. I didn't think 12" would be long enough and 24" would be cheaper. Although 24 inches was too long, I just removed the rubber grip and trimmed it down. The handle just slides on and the fiberglass shaft is now the perfect length and makes a great tool. I will never go back to a magnet cleaner.
