Quick Overview

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. 5,750 square feet of surface area. Resistant to clogging and greatly reduces tank maintenance.

Product Questions

I am looking to slowly trade out some of my rock in the display for marinepure in the sump to open things up a bit. Is there any ball park estimate on how many pounds of Fiji rock one of the 8x8x1 plates will replace?
Question by: wes on Jul 20, 2014 12:35:00 PM
Hey Wes,
Generally speaking the 8x8x1 plate is enough surface area to handle a 100g tank on its own, so you should have the ability to remove quite a bit of rock. Just make sure to do it slowly so that the tank has time to adjust and the bacteria that are getting removed have time grow in their new substrate.
Answer by: Bulk Reef Supply on Jul 20, 2014 12:35:00 PM
Is it best to cure the marine pure first and then seed it separately? Rather than just placing in in the sump? Or is either way good?
Question by: Curious on Jul 11, 2016 8:33:00 PM
Thanks for the question, and you can really employ the Marine Pure Plates in any way that you wish. You could cure, and seed the plate first if you want to however in our experience, we normally will just rinse the plate in a bucket of RODI water to remove any dust and fines that will be in the block, and then simply just stick it in the sump or where ever it is intended to go. The blocks are ceramic and that means there is no fear of organic matter, and therefore no ammonia.

I'm setting up a 300 gallon tank using 250 lbs of reef saver and 50 lbs of tonga plate for the display tank. If I wanted to add marine pure as a supplement for biological filtration to the sump would 1 8x8x4 be sufficient?
Question by: Christopher Peters on Jan 25, 2016 10:51:00 PM
Great question!
From the Marine Pure site 1 block will be just perfect for you!
http://www.cermedia.com/marinepure-technical.php
Answer by: Connor (Admin) on Feb 3, 2016 12:39:00 PM
Maybe a good addition would be to list on the description is how many gallons the 8x8x1 slab is rated for? Same with the 8x8x4 and each sphere, obviously some live rock will need to be used in the DT, but if I only want a minimal amount, knowing how much marine pure I can use in place of LR would be helpful, surface area isn't helpful as the recommendation is in pounds of LR per tank size.
Thanks, love the services you provide, and I am following the BRS 180 diligent each week.
Question by: Joe on Jan 13, 2016 11:31:00 PM
Hey there!
That is a great idea! In the meantime to help I have included a link to all of the information about tank size and marine pure size. It is divided by Nitrification (the same as live rock to convert ammonia to Nitrates) and Denitrification ( in an anaerobic environment to convert Nitrates to Nitrogen gas) Feel free to let us know if you have any further questions!

Answer by: Connor (Admin) on Jan 14, 2016 11:47:00 AM
What is the weight of the 8x8x4 block?
Question by: Staci on Mar 30, 2016 3:49:00 PM
Great question!
The large block will weight just under 3 lbs. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 4, 2016 10:23:00 AM
Can I put this in my fuge with about 5 lbs of live rock on top of it and still be ok
Question by: Ryan Edmondson on Jan 14, 2016 2:37:00 PM
Great question,
You certainly can add this into your refugium under the live rock. Depending on the placement the marine pure can work to replace the live rock as surface area for bacteria to convert ammonia into nitrate, or in low flow anaerobic environments can convert nitrates into nitrogen gas. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 14, 2016 6:30:00 PM
Do I need to cure this marinepure? Can I put it straight into my sump?
Question by: Fairway on Jan 14, 2016 7:09:00 PM
No answers yet. Be the first to answer the question!
Its seem this product could be used as both a denitrification tool and a nitrification tool. So with that being said should we purchase two, one for a high flow area and the other for a low flow area so that we can take advantage of both of its abilities? I'm thinking of using this product in a new 90g build with a large sump. Please advise how you would set that system up using this product.
Question by: Jason Craig on Jan 28, 2016 12:46:00 AM
Great question!
You can certainly use this in both high flow and low flow areas to create the different environments within the system! You can select 2 different plates in the different areas to attempt to achieve a low oxygen environment to help convert some nitrate into nitrogen gas. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 4, 2016 4:50:00 PM
I am thinking of getting an 8x8x1 plate of this to put in the back chamber of my AIO nano tank, but I don't think any of the chambers are big enough. Is it possible/adviseable to cut the plate down to size?
Question by: Mike on Jan 28, 2016 2:30:00 PM
This certainly can be cut or broken!
There is no positive or negative to using broken marine pure, the surface area will remain the same. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 4, 2016 6:19:00 PM
Will this media have to be removed at some point for cleaning?
Question by: Billy Danz on Feb 24, 2016 9:15:00 AM
Great question!
It does not need to be cleaned and can be left just as standard live rock would. However sometimes detritus and other elements can grow on it which may make cleaning nicer to keep the sump or area clean. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 24, 2016 2:51:00 PM
I want to add a block to my system. I have a JBJ45 gallon AIO tank with a trigger systems cube sump.
Can I put marine pure in the center section of the JBJ or down in the skimmer section of the sump? I don't want to put it in the refugium section as I'm concerned about the size
Question by: Bob Escher on Aug 12, 2016 2:38:00 AM
Thanks for reaching out to us! The great thing about these Marine Pure blocks is that they are pretty brittle and can very easily be shaped and cut to fit your exact needs! :-)
Answer by: Randy (Admin) on Aug 16, 2016 1:59:00 PM
Is there any way to cut an 8x8x1 plate?
Question by: Evan on Jun 19, 2016 5:24:00 PM
Sure is!
This is fragile enough to be broken by hand if needed, otherwise a simple hack saw can be used for an even cut.
Answer by: Connor (Admin) on Jun 21, 2016 12:45:00 PM
The product description mentions I can place MarinePure plates below the substrate in my new tank. By using this method versus placing them in my sump, how much (if any) of the plates effectiveness am I losing?
Question by: Andre on Dec 21, 2015 4:37:00 PM
Great question!
The performance will not change however the type of bacteria may change. With the buried media it will possibly harbor anaerobic bacteria which can convert Nitrate into Nitrogen Gas. If the media is left in a high flow area of the sump it will act just like standard live rock and harbor bacteria which can convert ammonia into nitrite and nitrate. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 6, 2016 6:09:00 PM
Researching these blocks online one of the issues could be leaching aluminum causing coral health issues. Have you seen any issues with this?
Question by: Chris on Mar 11, 2016 8:07:00 AM
Great question!
We have been using MarinePure in our systems for several years and many of us use them on our personal tanks. We have not found any issue from running the MarinePure. We have seen posts about testing showing a form of aluminum silicate however this has not impacted the health or growth of our tanks. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 11, 2016 9:23:00 AM
I am considering placing a bio block in my sump tank. How often and how to properly clean these blocks?
Question by: Dave on Jul 7, 2016 1:42:00 PM
Hi Dave,
There are a few different ways and methods to clean the blocks. First of all if you have passive flow going around the blocks you may never need to clean them. We do suggest every month or so giving them a rinse to remove any built up detritus and other matter that will settle in the block. I personally will just fill a 5 gallon bucket during an water change and give it a good rinse while swooshing it around in the bucket. Then simply just placing the block right back where I took it from. Others like giving them a rinse in fresh salt water a bit more often but that is most likely just more work than you need to do.
Have a great day! : )
Answer by: Charlie (Admin) on Jul 7, 2016 2:13:00 PM
Can the blocks be cut in a way that they won't crumble or fall apart?
Question by: Stace on Mar 12, 2016 7:28:00 AM
Great question!
These blocks can be cut rather easily with items as simple as a Hack saw. Unfortunately they are still a little fragile with the amount of surface area and breakage may occur while cutting. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 14, 2016 10:48:00 AM
Can I cut the 8"x8"x4" block into smaller pieces? It's really a big piece and takes up a good amount of space.
Question by: Mills on Mar 12, 2016 11:49:00 AM
Great question!
These can be cut using a hack saw if needed! Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 14, 2016 11:40:00 AM
Do you need to occasionally wash these down or clean them?
Question by: Mark Steffen on Jul 23, 2016 1:15:00 AM
Hi there,
It is recommended that they get rinsed once every couple months however not completely needed. We like to rinse them in a bucket of old tank water every now and then to release any loose detritus that may be trapped.
Thanks for the question and have a great day!

Does the Marinepure material absorb phosphates? I would like to add the Marinepure to my tank which has >5 ppm phosphates prior to removing my live rock that is loaded with phosphates. My challenge is that this is a 300g tank and I do not want to tear the tank down. Once I remove the live rock, my plan is to use your GFO.
Question by: Will on May 17, 2016 8:02:00 PM
Great question! Marine pure will function with surface area just like live rock and does not remove phosphate. The marine pure will work in conjunction with the nitrogen cycle to convert ammonia and nitrite. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on May 18, 2016 4:13:00 PM
I have a small sump but would like to place a 8x8x4 block on it's side rather than flat. Will this work this way?
Question by: Keith on Jun 11, 2016 11:05:00 PM
Hey there,
These will of course work as live rock media and can be placed in any position. Just serves as surface area for the system to grow healthy bacteria.
Answer by: Connor (Admin) on Jun 14, 2016 6:06:00 PM
I have read that MarinePure leaches aluminum into the water, i am going for minimal amounts of live rock in my DT. I would like to make sure that i have enough biological filtration in my tank by adding MarinePure to my sump. Have you heard of MarinePure leaching aluminum and what is your opinion on this? I am a big fan of BRS and really appreciate the information you provide, thanks in advance!
Question by: joe hall on Jun 12, 2016 4:26:00 PM
Great question!
We have indeed see the posts on the aluminum leeching however to that we have used MarinePure for several years on every office tank without side effect. While the test may still be out we have not found a negative impact of Marinepure and still recommend it for supplementing the biological filtration. Feel free to let us know if you have any further questions and we will be more than willing to help.

  • don't see why it wouldn't work By Ryan on 9/22/2016

    this has been in my tank for about 2 weeks, I bought the 8x8x1 block and have a 60G tank. its really light when you first get it but once you rinse it you can see how much water it hold. so far so good.
  • Arrived in great shape By Tim on 9/15/2016

    Will definitely order again
  • great product best customer service By hazmattec on 8/31/2016

    product looks great just getting tank and sump set up so hopefully it works as good. had issue with first one customer service took care of issue with no questions.
  • Appears to work By Greg on 8/22/2016

    VERY porous, very brittle also, so handle carefully. Mine came fairly intact, and was packaged well. Either it works really well, or my bio pellets finally kicked in, but my nitrates went from 15 to two in about a month. Great item for a sump, could be custom cut if needed.
  • Great By John on 8/3/2016

    Works perfect
  • Good but... By RC on 7/6/2016

    I purchased the large block about a month and a half ago for use in my new sump for my 125g. I am in the process of building a custom stand/shelf unit, so it is taking longer than originally expected. The wife wanted to get a smaller tank up and running so she bought me a 24g nano. I set it up, and placed this in the back (sump) for added filtration prior to adding anything else (filtration. I am running carbon and foam filter block as well. Now, I take blame for my mistake as I forgot to soak like the directions expressed, I only rinsed it off for about 10 minutes. With that being said, we went out and got a couple clowns and some cleaner shrimp. Within 4 days, both clowns were dead, the shrimp are still good. I have tested the water and all parameters are well within safe limits. I verified this with three experts (people who have been in the reefing hobby for a long time. This is the only thing that I didn't follow the directions on and I love two fish. I am not sure if I will use this again or not, but if you follow the directions and soak it like it says, maybe you will have better results. The last part, this is VERY VERY fragile, and I have "rubbed" quiet a bit of this off adjusting it in the sump and pulling it out. It looks like a good product, but I am not happy with it (partially due to my own haste).
  • Perfect! By Deanna on 6/28/2016

    I wanted an alternative to having pounds and pounds of rock in my DT and this seems the perfect product. I am amazed at how lightweight it is, too. Thanks BRS for the wonderful job packing the box for shipping, everything arrived in perfect order.
  • Next Gen Product By Chris on 6/11/2016

    First, buy it from a reputable dealer (like BRS). Rumor has it there is a cheap knock-off that has harmful elements. You can find video's about it on the YouTube...

    Great material. I bought a 1" plate to replace my biomedia for my 5 gal nano. It is brittle, so cut it carefully or it will chip all over you. I used a sharp knife and steadily worked through the plate with the tip, worked well. First cut I chipped a bit b/c I went too quick. Later cuts were easy. If you do chip it, you can easy superglue it back together.

    I will definitely be ordering more for use in QT and other tanks.
  • Never Again By Clement on 4/26/2016

    I was really excited when I learned of this product. I started by ordering a couple of the plates and eventually orderd a bunch of the 2 inch cubes on amazon. I was lucky in that I started with the cubes in a non DT tank. I put them in a high flow area. WITHIN 2 hours my acropora went from happy to no polyps. A week later and everything was starting to STN. I can fairly pin the blame eon this product because when I introduced it I did not change anything else in the tank.... No water change, no carbon change.... nothing. To be fair I did no rinse the product before placing it onto my tank. However, it did not cause cloudiness. Putting this product in my tank is the worst mistake I have made in over 5 years. NEVER AGAIN.
  • Fragile By Gus on 4/8/2016

    Marine Pure is a must if you have a sump. I was easily able to cut it to fit perfectly on my return chamber but is extremely fragile. I was placing it in the sump little debrie was coming and chips easily. still though great product.
  • Great product but breaks easily . By 120reefkeeper on 3/18/2016

    I would have given this a better review but mine arrived broken. The product is very fragile. One of the corners had snapped off and instead of reporting it I chose to use it as is. If I were to but it again I would buy the bigger blocks. It is a great product and holds a ton of water , but it's very fragile.
  • Amazing surface area very porous By Jeffrey on 2/18/2016

    These are perfect for the minimalist aquascaper. I am not a huge fan of huge piles of rock in my tank but really like having the beneficial bacteria from live rock...Marinepure is a great substitute for live rock and you don't need 100's of pounds of rock to do what these can do with one or two plates.
