just made a little frag rack using stuff i had lying around
There is a magnet cleaner that i dont use, a grill from an old filter and super glue
Then its as simple as gluing the grill to the magnet
had to cut it a bit smaller, give it a clean and in the tank
so now i am able to move the zoa that the hermit crabs keep attacking away from them and also attempted to frag a couple to see how it goes
