Matrix (and siporax) questions, to keep from derailing Sahin's thread.....

Just stumbled onto this thread a few days ago and finally finished reading through this. I think this is freakin fantastic! When I jumped into saltwater a few years ago after many years in fresh and wondered why nobody ever recommended the use of these filter medias in the sump. I always kept some in a media bag in the sump as I had tons left from FW days thinking it can't possibly hurt. I am going to be loading up my sump with this stuff and taking out the live rock.
Congrats to both rucnnefish and slin for successful implementation of matrix and siporax. I do wonder, if one has to dose phos and nitrates despite having a lot of fish does it not mean there's too much of the media in one's system?

My experience is almost similar - 10 liter Siporax in the coast to coast overflow 350 liter aquarium total.
30ppm nitrate and 0.08 phos to begin with- no bac additions except adding this media and two weeks later nitrate at 3ppm phos 0.00
I am looking forward to returning to my aquarium in a couple of months to see both the maturation of the media and to stock the tank with some SPS.
Maybe I might stack the Siporax in an orderly fashion if the filtration requires it.
Furthermore this tank has no live rock as you can see, I removed the liverock the day I put the Siporax in the coast to coast.

Adding a third to this mix... Eheim Substrat Pro?
Adding a third to this mix... Eheim Substrat Pro?
I know the saying three's a crowd, but I have to wonder. Has anyone here looked at Eheim Substrat Pro?
It is:
- made from the same material as Siporax, sintered glass
- has more total surface area per liter of the material when compared to siporax (but less than matrix):
https://www.rostlinna-akvaria.cz/te...rat-pro-vs-sera-siporax-vs-seachem-matrix-146
- form factor: round material = no cylinder holes for detritus to accumulate and easier to shake loose detritus from its container.
I have never used matrix in fresh (used the other two in fresh) and I had seen some online reviews that showed the lack of consistency in the type of stones seachem matrix packages comes with so I am thinking substrat pro might have something to offer here as well. I look forward to hear everyone's thoughts and experiences with this material.

I have seen it personally used the same way with success. There are others on the forum and other sites that have also.
I use it in all my FW canister filters, never clogs. Great stuff.
The Matrix is a naturally occurring mined stone, I don't think it really detracts from the performance. Most complaints I have seen state a color or some other superficial defect. I prefer Matrix and plan to add it in a large size reactor.
Here's a long-term follow-up on the effectiveness of siporax: About 1 year ago, I added 2 liters of siporax to the sump area of my SPS dominant 40B. I simply rinsed it in RO and placed the bags in a low flow section of my sump. It took a couple of months before I saw any significant reduction of my NO3. However, once it got fully populated it became VERY effective. After about 3 months, my NO3 dropped to nearly undetectable using a salifert kit and has remained super low. I've upped my feeding and still the tank barely budges above 0. Overall, I'm extremely pleased with this product.

Great information here.
I've tried to read through the thread but didn't find anything on a need to dose carbon to fuel the bacteria that are reducing the NO3 to N.
I understand that providing more anaerobic area for denitrifying bacteria will result in an increased uptake (hence overall aquarium reduction) of NO3 and PO4. However, I understood that if NO3 and PO4 are available, carbon becomes the limiting nutrient for these bacteria. Hence, we need to dose a carbon to keep these bacterial colonies going.
I don't see people mentioning any form of carbon dosing. It may be happening as a byproduct of something else such as algae decomposition?

siporax ≈ substrat pro ≈ matrix = pumice
siporax ≈ substrat pro ≈ matrix = pumice
I'm sort of the person who keeps digging a bit more once he starts looking into things. I sorta hit upon a eureka moment. One online review mentioned that Matrix looks like pumice stones. And I began to have vague recollections of what pumice is and decided to look it up on wiki...
Pumice "... consists of highly vesicular rough textured volcanic glass.. "
" It forms when volcanic gases exsolving from viscous magma form bubbles that remain within the viscous magma as it cools to glass. "
Even the origin of Seachem's product name "Matrix" can be found here:
"Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano....The simultaneous cooling and depressurization freezes the bubbles in a matrix...."
Seachem Matrix is a naturally occuring "porous stone" (quoting Seachem) that sounds and looks a lot like pumice (when it walks like a duck and talks like a duck.. ) while siporax and substrat pro are manufactured fritted or sintered glass that seems to basically emulate the physical properties that pumice has.
This isn't a knock against Matrix. There's certainly grading and cleansing process these will go through for various industrial or cosmetic applications and there are costs involved in that process. In fact I'd pick Matrix over pumice aggregate as the grading and cleansing has been done for me. Siporax and Substrat pro have physical forms that are advantageous to use in hobby applications.
My itch's been scratched.

Yes, it's Pumice. How ever finding the right kind with open cells instead of closed makes the difference.

How many bags of Matrix do you think i should run in my sump? I have a 75g display tank with a 30 gallon sump. No refugium section. Right now i have two bags of about 1 to 1.5 L of Matrix in that area. I think i have some room for a few more bags though. Thoughts? Just fit as much as i can?

From what i understand it takes about 3 months for the magic to start happening.

Hi, here is my setup of Siporax.
2x3,5L for 350 L (90G) tank.
23 of August it was start, nearly 4 weeks, no changes yet in PO4 and NO3.
Хорошего рифа!

Clean it in RO/DI.
I assume that medications where never used with it. That could cause problems.

Wash it , 24-48 hours bath in hydrogen peroxide , that help to burn all organic from Siporax.
Also I've been reading about microwave usage to clean Siporax, but I'm not sure if that is true.
