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.

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.

Added two quart box of spheres to my sump and am confident it is working. Easy to put anywhere and don't need nearly as much rubble in sump saving valuable space. I recommend. Thanks BRS!

Marine Pure Biomedia 1.5" spheres are an awesome product. They work perfectly in the back of my Innovative Marine Nuvo Nano 8 tank. They work so well I will be buying a larger quantity for my new 240 gallon SPS dominant reef build. They will make a perfect addition to the sump.
Price could be a little better and making them different shapes like live rock is an awesome idea. I have recommended them to friends and they love them also.

shaping marine pure like live rock and bringing price down might be the only improvements to be made.
Great alternative to plastic By Robert on 8/3/11

Washed them the night before and they were still wet the next day. Perfect for when the power trips during those rainy months in Florida. Very pervious product that works great in the sump. Using an Eshopps 300 Wet/dry and using 2 gallons of Marine Pure Ceramic Biomedia in the first compartment and 5 gallons of standard bio balls in the other. All spheres in the wet/dry are wet and are having impressive contact time with the trickling water compared to the plastic bio balls. Definitely going to save up order more when the timing is right!
BIOMEDIA By Derek on 7/27/11

There should not a thought process of wheather or not you will buy this product. If you watch the video, the product is what it is... just amazing. Bioballs... out of the question. It truly is unreal the amount of surface area the small ball with hold. Plus most of all the flow! Thank you for the video, it for sure helped with my decision.

I was having issues with ammonia levels on my 400 gallon koi temporary tank because the bio balls just werent enough for the fish load. I added one gallon of cermedia and within a week the filters capacity had went way up. My filter holds 27 gallons of bioballs, adding 1 gallon of these is probably worth 26 gallons of the plastic bioballs. I would highly recommend these, the capacity vs price they are still way cheaper then the plastic bioballs.
