I’ve been making my own magnetic frag plugs with scavenged aquarium magnets for over a decade. Despite a proclivity for magnetic coral bases, somehow, someway, Ocean Wonders’ magnetic MAG Disks have flown completely under my radar.
So you can imagine the reaction when my eyes first focused on this delightful small package, sitting innocuously on the products shelves of my local fish store. I was then equally floored to discover that the Ocean Wonders MAG Disks have been on the market for over five years!
Nevertheless, I quickly snapped up the package which consists of four ceramic discs with built-in neodymium magnets inside. Another four non-coated magnets are also included for placement outside the glass.
Together these magnetic pairs are capable of gripping on glass up to 3/8th of an inch thick. We have no doubt that these magnetic frag discs can hold frags and lightweight soft corals but you probably wouldn’t want to mount any large and dense stony coral colonies to your glass with these.
Reefers are always looking to maximize their real estate for corals and frags, especially with frag racks, many of them being magnetic. So the use of simply magnetic frag plugs is a creative way to mount your small corals and frags in original ways, and it may situate your corals in a more natural way, such as chalice corals in a vertical orientation.
