Have old magnets laying around from beat up algae scrapers or broken powerhead mounts? Try repurposing them. Those old magnets can be used to make large and small frag racks, probe holders, or even magnetic frag holders. Don’t just toss them out in the garbage, especially considerig how expensive the neodymium is becoming nowadays. If the magnets are cracked and rusting, we do encourage you to throw those away since they will cause more headaches than they are worth. If you just have too many that you don’t have any use for, try giving them away to local hobbyists. Chances are, there is someone close to you that is working on an inexpensive DIY frag rack or has some other use for them.
