Traditional coral frag holders are designed for frag tanks and made of egg crate, and if you ever put one in your display tank, they are an instant eyesore. Reef Rax has produced custom molds that simulate real live rock structures and textures at a fraction of the weight. 


Sandbed Rock

Place the rock anywhere on your aquariums sandbed or if you have a bare bottom, they are even better! Reef Rax's Sandbed Rock is made of a highly porous resin material that is 100% reef safe and can hold up to 6 frag plugs at any given time. The sandbed rocks are great for frag tanks or grow out systems that have a lot of loose coral frags on plugs. 


Dark Brown Color

Reef Rax custom dark brown coloration resembles dry live rock and is the perfect addition to any new aquascape. Over time coralline algae will encrust the rack creating beautiful purple hues, matching the rest of your aquascape. The resin that is used to produce Reef Rax is colored all the way through and will not change color if it is chipped or cracked. If your current tank already has coralline encrusted rock, we suggest using the Purple Reef Rax.
