My LFS mentioned the FL!PPER Platinum Credit Card Aquarium Algae Scraper to me, does it work effectively? I already have the Tunze Long which I use on the front and side glass of my Reefer 250 but need a long handled scraper for the back wall. I liked the idea of putting my old credit cards to use.
