over doing siporax

Bigzman... Where did you get those 1litre median age? My matrix didn't come with anything like that, and all the ones at my lfs are much smaller holes (more like for gfo or carbon) which I am concerned will prevent water flow through media and trap junk

Agree Wheelman76 reefvet stated that but the answer I have been looking for is the below which one is more surface area. Judging by their claims seachem wins by twice as much.

270 m² per liter Siporax vs 700 m2/L for Seachem.

I would be very curious to see how they're coming up with those numbers. The way siporax is made I'd be very surprised if matrix got anywhere near it in terms of surface area. You can tell by the weight alone...

A logical part of me agrees with you. But it is possible since they measure volume vs weight. There is more per liter in matrix vs siporax rings. Not so much in pond matrix. That do have some info on surface area on their site.

Not necessarily pertinent information or a good means to judge. For example --

ROX 0.8 Carbon is rated at "m2/g: 1225", that's 1,225 m^2 per gram of Carbon.

I forget who did the test, but Greg Carrol also posted recently that Matrix had the superior surface area. Can't for the life of me remember the thread, but it was by a pretty large margin IIRC.
 
Good point

Very good point. It is possible. I would like to find that data. From a results prospective I have seen my nitrates go from over 50 to .5 in 4 weeks.
 
I'd wager both Siporax and Matrix offer lots of benefit. Siporax has one major thing going for it -- it doesn't collect detritus.

I shake my Matrix around in the sump every few weeks/month. Only for a few seconds mind you, SPS seem to love all that nasty that comes out the return pump when I do that. Not sure what they get out of it, possibly just bacteria, larval pods? Who knows.

That is so very true. Coral love it on my old tank with no socks. New tank, If you note on my pictures I run matrix after 100 micron socks to greatly reduce built up. I still shake the bags as will as the loose pond matrix. Not much comes out of them after 3 months. I added more pond matrix and regular matrix. Won't be using siporax as I don't have access to the larger pond versions locally.

So you're basically running really fine mesh socks? I was thinking about that myself, I typically run no socks but once a month or so I try and stir up all the detritus that settles in the DT and Sump. I'll leave it in for a few days for good measure but within 2-4 days the standard Felt socks are clogged.

Correct. I have 32 socks and switch them out every 4 days. Granted it's a pain but will worth it. Skimmer / pump area are much cleaner. Also media and uv do not collect detritus. Also helps with tank clarity.
 
Can we use xxl coral sand ? It is also very porous and usualy much cheaper then siporax? /siporax is btw made in China and he are identical with many non branded similar sintered glasss media, they are all imported-manufactured in China/

I was not aware it was made in China. I get the sintered glass is effect but pumice aka seachem is natural. Only down side is buffering capacity is virtually none existent.

On another note I added 4 more liter of seachem matrix. I know it will take a while but hopefully this should help my nitrate stay near low with out carbon.

That thread was started after I took Sahin's tank thread off topic discussing Siporax.

I've worked in Aquaculture research for over 30 years and have used/tested Siporax and all the other sintered glass media since they came on the market.

You can probably have too much of a few things in a reef tank. Effective media for denitrification would not usually be one of them.

Siporax if run correctly is up to 37 times more efficient than live rock. Matrix about 20 times. Substrat Pro about 10 times.

Which to use and how is all dependent on what's in your tank and what else you're doing to handle excess nutrients.

Please Define what you mean by "if run correctly"!
