Live Rock able to convert Nitrates

[q]

I was reading on Albert Thiel's web site and he was saying that the anerobic bacterias live deeper inside the rock. Is this true and if so what is the amount that they contribute to the tank?
Second question is:
He stated that you don't want a DSB over 3 inches deep because of hydrogen sulfate accumulation. Not worried about it but it seamed to me that he thought that the LR would take care of the nitrates.
This is just some info I found and was a little different so I figured I would get some different perspectives on the topic.
Thanks

Although the bacteria needed to convert nitrates may be found deep inside rocks,water circulation is not.So there will be VERY LITTLE to NO nitrate reduction from live rock.The threat of hydrogen sulfates accumulating in home aquariums is also a rarety.I have never heard of a tank crashing due to this...

I guess it all depends on how porous the rock is.
I think that live rock will help in the reduction of nitrates but is not a total solution for most of us.
I have read and heard from others however that claim that good quality and a good quantity of live rock is all you need.

Lots of live rock is an effective way for nitrification. A dsb does not have much circulation either and it works.

Yes,I guess that is true..
