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.
- 100% Tank Tested
- Most technically advanced bio-filtration substrate
- High usable surface area for beneficial bacteria growth
- Open porosity means maximum bacteria exposure to contaminates and promotes excellent water circulation and less clogging
- Designed specifically to target ammonia and nitrite removal and minimizes nitrates
- Inert and chemically stable
- Greater than 80% open porosity
- Provides consistent water chemistry
- Reduces tank maintenance
- Able to support large fish loads
- Can be cleaned, reused and sterilized

Product Questions
Hello, I am starting a new tank with sump. I would like to use Marine Pure spheres in the refugium chamber. Should these be added from day one or added after cycle?
Question by: Robert Clark on Dec 4, 2022, 7:45 AM
You can put these in at the same time you start your cycle when you set up your aquarium. This will give the beneficial bacteria a place to grow and populate to help complete cycling.

Just wondering where in my sump I should put these balls? In the filter sock? Or just somewhere in skimmer or retun chamber? I dont have a refugium chamber in my sump.
Question by: Treg on Oct 22, 2019, 2:45 PM
Hey there!
You can really put them anywhere you like, as long as they stay submerged all the time.
Take care

How long would a box of these in a freshwater sump usually last before they need replacement?
Question by: Jess on Nov 25, 2018, 12:42 AM
We do not have a lot of experience with freshwater aquariums so it is hard to say how long they last, but you should really never have to replace them. You may need to clean them from time to time, depending on how much detritus gets stuck in the pores. Since they are made of ceramic, they should last almost indefinitely.

How many one gallon boxes of these marinepure spheres would you recommend for a system with a total water volume of 450 gallons?
Question by: Electric Reef on Sep 5, 2017, 6:26 PM
Hey there,
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?
Question by: Andre G. on May 29, 2017, 11:47 AM
There should be no issues with locating your marinpure in the first drain chamber. While marinepure can be brittle due to its highly porous structure, it can stand up to high flow without any problems, so long as it is not overly concentrated.
Happy reefing!

I was reading about marinepure leaching alumium into the tank which can kill corals. Is this a possibility?
Question by: Brian on May 27, 2017, 1:26 PM
This is a popular topic of debate over the last couple of years on public forums, and up to this point there have been no conclusive findings. We've actually be doing some research here at BRS on this very subject, but don't have any definite findings just yet. The issue is not only whether or not aluminum is leached, but whether it is toxic, and and what levels. This issue is mostly speculative at this point, and was raised because some people got their water tested and found elevated aluminum in their tank water, and suspected Marinepure blocks as the source. Whether or not they do leach, we don't know if this is an issue right now as we don't know toxicity, but what we do know for sure is that there are many, many successful reef tanks operating in the reefing community with Marinepure blocks, including several tanks here at BRS.
Happy reefing!

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
Question by: Brandon on Apr 24, 2016, 6:46 PM
Great question!
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.

If these are in the display tank with a Mandarin, will copepods breed inside the the spheres successfully and let the Mandarin thrive?
Question by: Eric on Apr 21, 2016, 12:06 AM
Great question!
Our tanks with Marine Pure do have thriving copepod populations and certainly will work well with your Mandarin.

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
Thanks!

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.

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.
Question by: Tim S. on Mar 25, 2016, 5:37 AM
Great question!
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!

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?
Question by: Eric Johnson on Jan 30, 2016, 12:26 AM

They can be run in a trickle tower or submerged! Feel free to let us know if you have any further questions!

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").
Question by: Oscar on Jan 23, 2016, 1:32 AM
Great question!
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!

Will these float if placed loose in a sump.
Question by: Paul on Mar 24, 2015, 3:28 PM
Great Question Paul! MarinePure Biomedia will not float, The media will rest on the bottom of your sump.
Answer by: Bulk Reef Supply on Mar 24, 2015, 3:28 PM
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.
Thanks
Thanks
Question by: rick on Jul 8, 2014, 2:58 PM
Hi Rick,
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.

are these suitable for fresh and saltwater?

Hi Pete,
There is no reason you couldn't use them on a freshwater system.
