Mark, I think I'm confused now.

I'm sugesting that any LR will not elliminate 100% of Nirtate do to the fact that anarobic zones in the LR will not be enough to handle most closed systems.
This is why so many other methods are developed to handle excess Nitrates.

Now I should preface myself by saying I'm hypothesizing via what i have read and the what seems to be a common theme, having to rid Nitrates for a tank
