- MarinePure Ceramic Biomedia 1 1/2” Spheres
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 1½” Marine Pure ceramic sphere has 240 square feet of surface area. This means you can fit almost 20 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.

Crazy surface area, can run frag tank with no live rock By Turtle on 3/7/2018Turtle would recommend this product to a friendI've got a 14g IM peninsula running as a frag tank with very little live rock. It was a nano reef for a little while and I added the spheres to the middle chamber in the back. Now there is hardly any LR in the tank and the Marine Pure is doing the grunt work of bio filtration. Soon there will be no LR in the tank.
They have so much surface area, that they float for a second when dropped into RODI to rinse off. Try that with live rock.
Best media money can buy By Mike on 10/12/2017Mike would recommend this product to a friendThis is the best media ever and doing some research 1 ball has as much surface area than 2gal of bio balls will never buy any other media again
Excellent Stuff! By FLSharkvictim on 5/25/2017FLSharkvictim would recommend this product to a friendI have a 120 Mixed Reef, that has been up and running for over 5 years! I added a 1 8''x8''x1'' plate and1 bag of these Spheres balls in my refugium and all is well. No spikes in any of my parameters and everything else is looking solid. Highly recommend~
All good By Steve on 11/9/2016Steve would recommend this product to a friendI like it Im trying it out and I can tell a different already
Work great By Martin on 10/22/2016Martin would recommend this product to a friendFits in tight spaces and smaller fuge.
Great product By Scott on 10/11/2016Scott would recommend this product to a friendI keep putting more and more of this stuff in my sump as time goes on. About a month later I see a decrease in nitrates as a result. Even with a big eel, I've almost completely eliminated carbon dosing while maintaining nitrates around 5. I believe in this stuff whole heartedly.
Be Careful By Will on 10/5/2016Will would recommend this product to a friendI bought the 1 gallon spheres for my sump. I have a 40 gallon breeder and 90 gallon tank. So I'm guessing around 100 gallons all together. I had about 50lbs of live rock in my sump. I wanted to change it out with the round spheres to get away from the bulky sharp Rock. That would snag my filter sock, hit the glass when working in the sump and for eye appeal. When I received the media I dumped them in a bucket with RODI water and begin to mix them and stir them up. After rinsing them well I removed them from the bucket water. I then removed the live rock from the sump and put the spheres in its place. After a few days I noticed some corals looked a little different and didn't think anything of it. The following day I seen a dead emerald crab and a hard coral completely bleached out. I figured something was wrong because my tank was perfect before this. I grabbed all my test kits and went to work. My ammonia was raised a little but my Nitrates went through the roof. I'm assuming this was because of the removal of live rock and adding the Marinepure.
If I were to do it again I would probably take out 1/4 of live rock and add 1/4 of Marinepure. Just to gradually change it out instead of the instant shock of adding so much new media in. I hope this helps someone else so you don't have to learn from $400 in dead corals like me. At least it was only minor instead of my whole tank.... BTW the next day I did a normal water change and things are getting better already.
excellent By drdom on 7/30/2016drdom wouldn't recommend this product to a friendi have a box of these in a sump in a 30 gallon isolations system. push came to shove and i had to significantly overstock the tank. i use this system for acclimation so i admit it is up and running for about a year. no substrate and a few pieces of live rock ... maybe 5 pounds. i had to place a yellow tang, mimic tang, sailfin tang, moorish idol, 3 scissor tail darts, 3 blue gudgeon darts, neon dottyback, randal's gobies, two spot gobie, lawnmower blenny, and a shark nose gobies in the system all at once. believe it or not.. after 3 and 6 days, the ammonia, nitrate and nitrite levels were perfect. i had those fish in that system for 3 weeks, did 2 water changes and all did well. i know it could only be due to the biomedia that i got this lucky. i am buying more today for my other systems!
Ceramic Dust/Particles By Rick on 6/8/2016Rick would recommend this product to a friendI run a BioCube 14 reef tank and am using these in filter chamber #2; in other words, there is no sump unit separate from the aquarium. This is a bare bottom aquarium set-up (no gravel or other substrate in the tank) so larger-than-microscopic detritus of any kind is clearly visible on the tank bottom. The ceramic spheres do continuously slough-off small sand-like dust that settles on the bottom and is difficult to remove completely. The spheres are located in a trickle filter chamber so there is no tumbling action whatsoever to generate this dust. There is little doubt that these provide excellent biological filtration but the dust factor is just something for anyone running a bare bottom nano w/o separate sump to take into consideration when they purchase. (And, yes I did rinse them thoroughly in accordance with the product instructions prior to putting them into the system).
Great dynamic product By Carlos on 4/27/2016Carlos would recommend this product to a friendLooks great, holds a ridiculous amount of water which clearly indicates it has great surface area. Also it aesthetically pleasant to the eyes compared to other surface area media I've come across.
Very porous !! By 120reefkeeper on 3/18/2016120reefkeeper would recommend this product to a friendThis is a really good product and so far I'm really pleased with it. This is a very very light weight product but it holds an incredible amount of water!
Awesome product! By David on 2/29/2016David would recommend this product to a friendBest media of this type on the market period. Excellent flow thru the media
Just curious how many I would need to fill the BRS frag tank kit you used to sell getting a used one next week and thought about trying the spheres
You would only need 1 quart of the spheres for filtration. Keep in mind the spheres are quite large and will take up quite a bit of space.
I was reading about marinepure leaching alumium into the tank which can kill corals. Is this a possibility?
How many one gallon boxes of these marinepure spheres would you recommend for a system with a total water volume of 450 gallons?
Thanks for getting in touch with us in regards to how much of this product to use. I would recommend that you fill any extra space with this media, as the more you have the better when it comes to biological filter space. I would however consider putting them in large media bags encase you need to remove them for maintenance. Thanks
I have RedSea reefer tank that has a small chamber where the water falls from the tank - this is just before the socks. Can I place the spheres there, or will they be pulverized by the flow coming from the top?
Will these spheres affect the water PH?
These will not change or alter the pH in the aquarium. Feel free to let us know if you have any further questions!
Do the ceramic balls need to be submerged completely in the water or can they be on the media tray and have the water continuously dripping on them?
They can be run in a trickle tower or submerged! Feel free to let us know if you have any further questions!
Question -- Why isn't this offered in a third, smaller size? Many people with nano reefs would love to run this. I've got a 12g Cube and I'd love to have 5-6 of the spheres or a couple 2" cubes in my hob AquaClear 'Fuge. Feels kinda wasteful buying a box and using 1/10 of them.
Marine pure can easy be cut to size if needed as well as using the smaller 1.5" spheres. Marine pure currently does not offer a smaller package than the spheres for total amount but may be something they can release in the future! Feel free to let us know if you have any further questions!
Is there an equivalence of this media vs dry rock? I know it depends on the rock type shape etc, but any rough estimates for pukani, Fiji or Reef Saver for example? Let's say if I have a 100G tank, in "theory" I would need somewhere around 100lbs of rock. Let's say I only want to add 50lbs and use this media to substitute the "missing" rock. Is there an equivalence of surface area between the rock and this media? I basically want to know how many I should add to the sump to offset the missing rocks.
I hope I made myself clear :S
I have included a link to the Marinepure website with the technical data. This will list exactly how much Marine pure will replace live rock for varying sized systems.
Starting up a new 60 gallon tank. Planning on putting Marinepure in sump. Where is the best place in my sump? Was thinking the refugium section(6.5" x 11.5").
We would typically recommend placing the marine pure in the refugium or sump section with average flow to added over the media. Feel free to let us know if you have any further questions!
If these are in the display tank with a Mandarin, will copepods breed inside the the spheres successfully and let the Mandarin thrive?
Our tanks with Marine Pure do have thriving copepod populations and certainly will work well with your Mandarin.
Are these suitable for fresh and saltwater?
There is no reason you couldn't use them on a freshwater system.
Do you know how many of the balls are in a gallon of them or how large of a physical area they would take up? ie. 1 gallon 8"x10" one layer deep.
There is going to be roughly 75-100 ceramic media balls in a 1g box. If you have an 8x10" area and only want one layer of the balls, that is about 80 square inches. Each ball takes up about 1.5" in each direction so you could be able to have 5 rows of 6 balls in that area (only about 30 balls). If you have a flat square area that you only want to put a single row of them in, I would suggest looking at the block as well.
