Siporax
 

Hi
For those using siporax where did u get it? Are there any Canadian vendors?
Cheers

I bought it off eBay from Austria. This was the cheapest I could find including shipping. I don't think there is a Canadian vendor.

I bought from the same place as Mindy.

Any recommendation between the 15mm and the 25mm rings?

I got it from the Austrian guy too. Honestly if I did it again I would just get Matrix or MarinePure blocks or even SubstratPro, I don't know it really makes a difference they all have tons of surface area likely way more than we need.

Independent testing by a biologist on RC found Siporax to be more effective at hosting anaerobic bacteria than Marine Pure and Matrix, so if you have limited space Siporax is the best bet. Otherwise it's just about volume.

I used 15 mm rings.

I don't understand, one of the first suggestions I get from this hobby is to get rid of the bio-ball/bio-medias, cause they can become a nitrate factory.

Do things work differently now and seems everyone is doing minimal rock work with bio-media?

It's so backwards isn't it? Bioballs are no good because they don't support anaerobic bacteria - that's the stuff that lowers nitrate and phosphate when you carbon dose. It seems like porous bio medias are quite good at hosting anaerobic bacteria. Back in the day there were trickle filters that some people said reduced nitrate - now we know why. :)

Thanks for the link!! Any rule of thumb for how much siporax per tank volume?

Thanks for the explanation Mindy, Berlin is so old school now :lol::lol:

Does that mean any bio-medias can work cause they are definitely more porous than LR, Why not buy something cheap like:

rather than the more expensive and hard to get Siporax? Is it proved Siporax work much better than other bio-medias, if so how much better?
