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

Ready for the tank, adding 50L tomorrow.

Im still not sure how siporax and the associated bacteria deals with phosphates. Is it simply reducing phosphates by approximating redfield ratio with nitrifying and denitrifying bacteria consumption. As nitrates are reduced by siporax and the associated bacteria inhabiting its pores, is the phosphate reduced approximately 1:16

Or is something different going on


Good question I was going to ask a similar one myself, I've always kept up to date on this thread and believe just about everything has been covered except this.

Hopefully Reefvet can help with this one.

We all know live rock can trap and leach phosphate. So how do we know if the bacteria on the siporax is actually processing the phosphate or whether peoples drop in phosphate is just due to it being trapped and possibly start leaching once it hits saturation?

I think you hit the nail on the head.
 
I have 4 24 Gallon tanks as my sump, One has 3510+ pieces in it. another one has 270 pieces in it with 4 media Blocks.
 
Like this:













That was from back in the thread a bit...



Then you rub it in. LOL On a more serious note I wonder why there is not (or I have not seen or found) a summary of people's essential REEFKEEPING practices available on each person's ID or intro's to their threads. Because it is a lot to read and not all the info is relevant nor easy to find. Thought of a few abbreviations which I think many of you could probably improve. SOWITERK Summary of what I think essential RK . Summarized RK (SRK) and so on . Maybe not the best place to post this but your wits inspired me. Thanks again.

My thought on this---

The Siporax doesn't accumulate detritus like live rock does so it doesn't create PO4 pockets or break down like live rock can over time. The detritus is more likely to be exported in heavy loaded Siprax systems, so PO4 is never as problematic as in full live rock setups. In other words, it doesn't eliminate PO4 but simply doesn't allow it to prosper.

A system that is all Siporax and just a few pieces of live rock in the display is likely to never have a PO4 issue.

If Siporax is put in to replace live rock, you're essentially removing some of the P04 factories (live rock) for a media that won't allow PO4 to accumulate.
 
Hello all-

So, I am a little confused about if I am using my Seachem Matrix properly, and am hoping that someone could give me some feedback? Currently, I have 8 liters of Seachem Matrix sitting in a slotted, plastic bin, in the return section of my sump:





I have been reading some conflicting comments about the effectiveness of this setup. It was my intention to place the media in the last section of the sump (after the skimmer and filter socks) to do as much as possible to avoid detritus settling in the media. Also, my idea was that by keeping the flow on the lower end, and having a fairly deep layer of Matrix, I would be creating a stable area for denitrification to occur? The media has only been in the sump for four weeks, and it is my understanding that it will take about three months to become seeded and start reducing NO3? I do have the option of placing the Matrix in a Zeovit reactor in my garage that I am not using, which would basically be using the media as instructed on the packaging.

I have quite a bit of live rock in my display tank (150 pounds in my 150 gallon display), so really am looking to use the Matrix as an additional area for denitrification.
 
Just wanted to update my post from a few days ago:

Went ahead and moved two liters of the Seachem Matrix I had sitting in the return section of my sump into an old Zeovit reactor that was sitting in the garage:







Honestly, I was pretty surprised how much detritus had already settled into the slotted bin sitting in the sump, as when I went to scoop out the two liters I was going to place into the reactor, I basically had a cloud of detritus explode into the sump...

I like the idea of using the Zeovit reactor, because I can give the media a "pump" once a week to dislodge any detritus that has settled in the media.
 
I know Seachem recommends 500ml per 50 gallons. So for a 90 gallon tank a litre should be good. Would running say 5l increase the anaerobic functionality enough to deplete nitrates?

I don't really want to carbon dose to get nutrients down.
