Brightwell Aquatics Razor Freshwater Algae Scraper

Brightwell Aquatics Razor Freshwater is a blade-style algae scraper for removing tough calcified deposits from glass aquariums. The replaceable razor blade cuts through green spot algae and calcium buildup that standard pad scrapers won't touch, without scratching borosilicate glass. Works on glass tanks only — never use a razor blade on acrylic. Keep spare blades on hand, since a dull blade drags and smears more than it cuts. The blade angle and ergonomic handle make it effective in tighter corners than most commercial scrapers.
