Want to frag your corals but have no where to place the frags?  MAG disks will secure your new coral frags to the sides or on the back of your tank or even on overflows, the locatons are nearly endless with these mag disks.  They are perfect for the hobbyist who only has a few frags or does not like the look or have the room for frag racks inside the tank.

Made with super strong epoxy coated Neodymium magnets and 100% pure Caribsea reef sand.

Works on tanks with a wall thicknesses up to 3/8“ thick.
