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!
http://www.cermedia.com/marinepure-technical.php
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
I didn't do what the instructions said, all I did was rinse the plate for 1 minute. Am I fine? Also this thing is making lots of dust in my sump. Is that normal? My tank was recently setup.
Question by: Anthony Almirall on Dec 18, 2016 10:18:00 AM
Great question! The purpose of rinsing is to remove those dusty fines that are in the block. If you have some left over after rinsing, you will be fine. :-)
Answer by: Randy (Admin) on Dec 22, 2016 6:25:00 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
Can this material be cut or broken to a specific size?
Question by: Adam Bouziane on Nov 27, 2016 7:59:00 PM
Great question! This material is very soft and very easily shaped to fit your needs! :-)
Answer by: Randy (Admin) on Nov 28, 2016 8:11:00 AM
Quick Question.
Would you guys prefer this media before or after cycling of a new aquarium?
Is there any difference on wheter i put it in now or wait til' the cycling period is finishe
Question by: Alexander Lor on Jan 8, 2017 10:37:00 PM
Great question! Either way will work just fine. I typically use them right from the start, so that they populate with beneficial bacteria with the rest of the tank. :-)

Thanks!
Answer by: Randy (Admin) on Jan 10, 2017 12:05:00 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!

Answer by: Connor (Admin) on Apr 7, 2016 10:36:00 PM
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 want to purchase some MarinePure I have a 150 gallon tank would one plate be enough or should I
get a block, is there such thing as over kill?
Question by: Richard Davis on Nov 30, 2016 10:14:00 PM
Great question! Ceramic media like these add additional surface area for beneficial bacteria to colonize and live. These surfaces exist in both live rock and sand in our tanks. This media acts much like adding more rock or sand would. There isn't a point of overkill, nor a recommended amount per tank volume. As a reference point, our BRS frag tanks have (8) 8x8x1 blocks as it's only bio-filtration. :-)
Answer by: Randy (Admin) on Dec 13, 2016 8:38:00 PM
Hello BRS. I would like to put 2 of the 8x8x1" MarinePure blocks into my Emerald 39 Sump. I was thinking of putting them on edge standing up on the baffle between the skimmer and fuge sections, where the Trigger symbol is cut out. This would put some in a higher flow area and some in a low flow area. I am running about 4-5 x turnover through my sump with about 130 gallons of water in the system.

Question is, will these allow enough flow through the sump or will they block the flow through the Trigger symbol and cause the water to flow over the blocks?

Thank you.
Question by: William Swartout on Dec 1, 2016 2:23:00 PM
Great question! Ceramic media could be thought of much like adding more rock to your aquarium. With this in mind, as long as the media is in the water column it will be an effective place for beneficial bacteria to grow and colonize. With the location you are suggesting, you may find the media becoming clogged over time and impeding the flow through that section of the sump. :-)
Answer by: Randy (Admin) on Dec 13, 2016 8:44:00 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.

  • Who Knows By Chad on 3/25/2017

    I think it's working? I have a small plate in my sump to help with surface area. I am not sure if it is helping reduce nitrates but maybe helping to hold them steady? I don't routinely stare at the sump so I haven't noticed any bubbling from it. The loss of a star is due to A LOT of fines coming from it, even after rinsing it for a solid 20 minutes.
  • Worthwhile, but fragile By Greg on 2/26/2017

    Used this to replace foam in my Reefer 250 bubble trap. This stuff is very delicate -- I ordered two. one arrived broken in half... and they're delicate to the touch. Don't put them somewhere that will subject them to mechanical agitation.
  • Super BioFilter By Jeff C on 2/16/2017

    If you're not using MarinePure to supplement your biofiltration, why are you still waiting? This little 8x8x1 block will substantiate 30gallons by itself, that means you don't need as much in the display, giving you the best opportunity to play with your aquascape and get creative! I have a 46g Bowfront and 1 block of this and had a blast getting my scape perfect for our home!
  • Easy to work with By SPPF12- on 2/4/2017

    I have a Red Sea 250. I cut this in half and then soaked it in RO/DI Water. It's crazy how much water it holds. I removed the black sponge that comes with the Red Sea sump and about cut it to make a 2.5" x 14" strip. I cut the marine pure to the to be 4"x by about 14" to be the same same length as the bubble trap. . Now I have the Marine pure just under the sponge in the bubble trap area. :IT its great and while it is fragile it's very easy to cut to the shape you want. I recommend the 8x8x1 for the Red Sea 250.
  • marinepure ceramic biomedia plate By Chuck on 12/13/2016

    So far so good. I will be checking the water next week. Fit in my sump easy.
  • It works.. By Big Joe on 12/1/2016

    I have had the 1" plate in my sump, located in the baffles where it can get the most water flow and my nitrates are practically zero.. I thought it was the test kit, so I used another test kit and still almost no color in the test vial...I wont say it zero, because the first two color options look the same to me (being color blind sucks..lol!).. As for the plate, it was delivered with a corner broke, but since it was to go in the baffles anyways it really didn't bother me. The only downside, for me that's is aptasia loves to grow on it..
  • Way too fragile. By Doc on 10/1/2016

    I purchased a block to live in my sump. I have a 180 mixed reef and a 75 gallon custom sump. I can see how the product has a large surface area and would support lots of bacteria but the block I purchased was loosing material and the bag was full of fines. The product has little structural integrity kind of like a sand castle. I was expecting something solid. For the price one would be better off buying a bunch of dry live rock. This stuff is way overpriced. I wonder if it will erode down to nothing.
  • 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
