The new KENT Marine Pro-Scrapers with multi blades are probably the most professional high quality scrapers on the market. They ideal for removing coralline algae and calcified deposits in glass or acylic aquariums.
The stainless steel blade is rust-resistant and provides for smooth scraping. The Plastic blade is for acrylic or delicate glass for general algae. And the fabric pad covered blade for fine cleaning and mopping.
With new floating handle and now with an interchangeable head to use on other length pro scraper II. Handle and blade attachments made from strong ABS plastic, these units will not rust and resist breaking.
Pro-Scraper II metal and plastic blades are interchangeable and replaceable.
