I was just wondering if there are certain scrapers out there that people actually trust to not scrape their acrylic? I have been using an old credit card but that is such a hassle but I’m so paranoid about scrapes. This is why I didn’t want to go with acrylic but here I am with an acrylic tank. I realize a lot of the issues come from things like sand grain getting stuck in them but that’s not always the case. Anyway let me know what you use and you experience with it if you could please.
