Product Description

Nano-Tech Bio-Plugs don't just hold coral frags—they help filter water and feed corals!

These are no ordinary frag plugs! They are Maxspect Nano-Tech Bio-Plugs—which are made out of the same porous ceramic beads as Maxspect’s popular Bio-Blocks and Bio-Spheres.

So sure, they look cool. And sure, the embossed Maxspect logo on top is a nice touch. But the real selling point with these plugs is that they also serve as bio-media! Beneficial bacteria can colonize inside and on the surface of the plugs which helps keep your tank clean. Since Bio-Plugs are full of pores that are permeable by water, they actually make it easier for corals to extract nutrients from the water column compared to standard, run-of-the-mill frag plugs.

Maxspect Nano-Tech Frag Plugs are truly in a class of their own. They are the first frag plug that actually helps grow corals faster and healthier! Don't believe us? See for yourself by checking out this article from our friend Richard at Afishionado Channel. 

Features We Love:

  • Purpose-built for maximum efficiency with a clever 2-in-1 design: it holds frags and filters water!
  • It's made from the same porous ceramic structure as Maxspect's hugely popular Bio-Blocks and Bio-Spheres
  • Nano-Tech Bio-Plugs fit in most standard frag holders, racks, rocks, and coral transporters—you don't have to buy anything extra or proprietary to use them
  • You can use these multi-purpose frag plugs with another multi-purpose Maxspect invention: the Maxspect Fragnifier!
