About This Item

Details

  • Great for use with all fish and inverts.
  • Colorful mushroom-like stone helps your tank look full and mature while leaving more open area for your finned friend or invert to roam.
  • Realistic-looking rock offers high porosity and helps reduce ammonia to mimic your fish’s natural environment and aid in the biological performance of your tank.
  • Made with an aragonitic base material that’s free from cement and requires no curing.
  • Infused with spored, live bacteria that comes to life and helps improve cycling when placed in water.

Got this for my 125G reef tank as i was lacking in live rock and i know others said it was broken., mine wasnt. I had to break one of them to get it to fit right but overall great. I hope it didnt kill too many of the spores breaking a part of it.
