Jeremy, I'm guessing you probably use the various products (coraline scraper, algae scrubber, etc) quite a bit more than the rest of us simply due to all the tanks you're servicing. So I'd like to ask how often do you replace these? I ask because my nice coraline scraper has rounded out, and I can't remember off hand how often I used it. As wonderful as it is if I have to replace them every few times I scrape off some coraline I might need to find a different product (even though there's nothing out there like it), or maybe I'll try to put an edge on it again *shrug*
