- Ceramic Biomedia 2" Cubes - MarinePure
Why does BRS recommend this?
Biological filtration is the number one key to a nice and stable reef tank, and anytime we can sneak in some MarinePure Biomedia into an All in one tank, sump, or even overflows we will. We have run density tests and they have proved to be more porous than any live rock we could find. They are a great base for sponge growth, microfauna, and even coral frags.
MarinePure is an inert ceramic material with open flow architecture, extremely high surface area and natural wetting properties. A Single 2” Marine Pure ceramic cube has 720 square feet of surface area. This means you can fit almost 60 times the surface area in the same space verses bioballs.
The media’s composition is similar to natural rock formations. MarinePure provides approximately 150,000 sq. Ft per cu. Ft (510 m2/L) of accessible surface area. The properties of MarinePure create a stable home for a dense population of beneficial bacteria that remove ammonia and nitrites from your aquarium. Some systems will also see a decrease in nitrates. MarinePure will work in sumps, trickle filters, wet/dry filters, hang on the back filters or directly in the tank.

Due to the fragile nature of the MarinePure Cubes we are unable to guarantee that every peice will be an exact cube in shape. During shipping and Handling the cubes can be misshaped or damaged which will not affect the overall performance of the MarinePure Cubes. We highly suggest rinsing the cubes before use.
Cubes galore, but still not as much as advertised By Lucas on 10/18/2019Lucas would recommend this product to a friendI'm a big fan of this media and the flexibility it provides in display-tank aquascaping. The media is quite fragile but that is manageable. I've had the 4x8x8 block for a couple years and it's still in good shape, and did not deteriorate like some of the other brands.
My only gripe, as a math minded person, is that even though there are more cubes than most people would ever need in this product, it is not even close to the amount advertised. I received 77 cubes, which is on par with the other reviews of this product. If my elementary math serves me correctly, at 2"x2"x2", that is 0.356 cubic feet, which is only 71% of the 1/2 cubic foot being advertised (the smallest box offered at this time). 108 cubes would be 1/2 cubic ft. The box itself is 12x9x9 so the box isn't even capable of holding 1/2 cubic foot of fully intact cubes.
Having said that, I am VERY pleased at the condition they arrived in. No crushed or broken cubes at all. Also, even at 71% of the advertised amount, the cubes are still the cheapest per square foot equivalent of all the ceramic media options I looked at. These are less than 1/3 the cost per square foot equivalent of the Marinepure 8x8x1 plate, for example.
I would still recommend this product.
It works! By Ryan on 10/12/2019Ryan would recommend this product to a friendI started a reef tank using some great centerpiece-type texas holey rock. Since it isnt as porous as some of the other, more customary reef rock I had to supplement with marine pure. So far, so good, as my reef is 5 weeks in and properly cycled. I have about 30 cubes in the fuge and filter and each time I test there are no nitrites or ammonia, despite heavy feeding schedule.
Yes, you get A LOT of cubes in the 1/2 cubic foot box By Gerald on 11/25/2016Gerald would recommend this product to a friendI too thought the 1/2 cubic foot box would have maybe 12-15 blocks. When I opened the box I was astonished. I didn't count them all, but it has to be at least 70 blocks. I have enough to stuff my filter compartments in my existing tanks, plus a half box to spare.
Alot more than I thought By Eric on 9/15/2016Eric would recommend this product to a friendGoing off the Q&A for this product I was expecting about 20qty 2" cubes in the 1/2cuft that I ordered. I received 68 full cubes and 10 partial 50%-75% cubes. I had to go back and check the box to make sure I wasn't sent 1cuft by mistake, not the case, I received 1/2cuft. I provided the break down of full cubes vs partials since that seems to be a concern to some people, however I am please with what I received.
Since I haven't seen them in action my review is based on first impressions. I've had bio balls in the past, marine pure seems to be a better product hands down. Like other reviews on the other form factors of this product have mentioned - they hold a lot of water. I can also see how people running bare bottom might have an issue with sediment caused by the cubes, for the most part proper location to allow settling in the sump should work just fine.
I'm currently setting up a new tank and getting back into the hobby. My plan is to fish-less cycle with pure ammonia in a container with these marine pure cubes while I get everything else ordered, setup, plumbed and running. This way in a few weeks when the tank is setup all I have to do is transfer the cubes to the new sump and I should be ready to go very quickly.
If this product works 1/2 as good as they claim (and at this point I don't see why not) it'll be the new standard for bio filtration. I will post another review if my opinion should change.
I currently use live rock rubble and large pore foam as a transport method to move pods from my fuge directly to the display. This has worked wonders for my mandarins and pipefish. Are pods attracted to these?
The Marinepure works amazing as housing for Pods and will be a fantastic addition. Feel free to let us know if you have any further questions!
How many 2" cubes come in the marinepure ceramic bio media .The dimensions for my sump are 7 1/2"x9",should I get the 8x8x4 and cut it or use the cubes?
These will come with around 20 cubes. The 8x8x4 might be easier to work with as it is a single block. Feel free to let us know if you have any further questions!
I have the cubes in my sump. Do u have to clean them over time? Or does it act like live rock?
Over time there will be an accumulation of detritus within the structure of the cubes so periodically swishing them in a container of tank water would be a good idea. You should also avoid placing them in an area that would encourage algae growth that would quickly close up the pore structure of the media.
Can you list the actual count of cubes per box for each of the sizes you are selling ?
MarinePure Ceramic Biomedia Cubes - 1⁄2 Cubic Foot = _________
MarinePure Ceramic Biomedia Cubes - 1 Cubic Foot = _________
MarinePure Ceramic Biomedia Cubes - 2 Cubic Foot = _________
And add any additional detail about size and count that could be helpful
Ex. Brings 6 cubes @ 1"× 1"
I looked around and their is some conflicting info on some sites.
There is not an exact amount of cubes per box as the weight and size of each cube will vary slightly. On average there are
MarinePure Ceramic Biomedia Cubes - 1⁄2 Cubic Foot =25-30
MarinePure Ceramic Biomedia Cubes - 1 Cubic Foot = 75-80
MarinePure Ceramic Biomedia Cubes - 2 Cubic Foot = 120 +
I keep reading about how many square feet each of the various cubes represent, but I'm curious how that corresponds to something like a similar sized piece of various reef rocks, or a similar volume of sand.
It's easy to dazzle with numbers "look at how large this number is!" but without a point of reference it's hard to see how useful this is.
Also assuming it's super useful, will these majorly restrict water movement? So if I put one block along the width of my sump would water back up behind it?
