  • Great Product By Conny on 11/15/2014

    Works as described. Great way to increase bio - mass in the sump. Easy to work with and stays in place.
  • Marine Pure Ceramic Biomedia By Ojake on 9/7/2014

    Bought a gallon two weeks ago to go in my frag tank as extra biological filtration. Love the way they support the egg crate when spread out. Be sure to rinse prior to use to get rid of dust and fine loose particles. Will let you know how they hold up.
  • works great By matthew on 8/23/2014

    Will never go back to bio balls
  • Very porous and lots of are in a small package By Ronstopbl on 3/4/2014

    Replaced regular plastic bio balls in my sump tank and what a difference these things made! Zero detectable nitrates! Lots of little critters hanging out between them! With limited space for live rock, these are the next best thing!
  • Marine Pure Bio Media By Mark on 1/9/2014

    I have been using this product for over 2 years. I found them superior to plastic bio balls as they don't clog or cause elevated nitrates.

    I highly recommend

    You need very little compared to plastic bio balls, surface area of this product is amazing
  • Awesome bioball replacement By Sheen on 12/27/2013

    I've been using this product for my reef tank for over a year now and it's working great. It never needed to be take out and washed, it seems to stay clean without any maintenance. I was worried that the pores would be clogged eventually but it wasn't the case. It does produce some sand like particles that settles under the sump.
  • A Great Idea By lobro4 on 12/8/2013

    My sump has limited space. I am using these in lieu of sand. If they should get too gross, they are easily cleaned and ready to serve again. Lots of porous surface.
  • Incredibly Light By Jonathan on 6/13/2013

    From looking at the pictures you would not know just how porous these are. They feel almost as light at Styrofoam which should give you a better idea.
  • Better then your standard BB By Zombie Rock on 5/24/2013

    Replaced standard BB, prevent N factory! Must have!
  • Excellent Product By Bosley on 3/15/2013

    I have these in my sump/refugium I feel they do and excellent job all my water test reading are checking out great. In the past I used plastic bio balls sometimes struggled with high phosphates and nitrates. Not knocking the plastic ones I just really believe in this product. My experience I give it thumbs up.
