Review on Seachem 3-in-1 Algae Scraper - 18 Inch Retractable & Adjustable Aquarium Cleaning Tool by Crystal Robinson

Very easy to use and well made. I wish it had more than one blade. I have a glass tank, but most of the time I use a plastic scraper. Use the steel blade only when stubborn algae need to be removed. Some have complained that the blade has rusted after a few uses. I remove it, dry it completely with a paper towel and store it separately until I need it again. In addition, the scrubbing part is very suitable for walking on the glass to remove loose algae. Too bad there wasn't a 24" or longer version.
