+1, LR is always better.

But if you keep the bioballs, as long as the flow through them is sufficient, things should be ok. But if you want to spend a few bucks, get the LR

The way that I was explained is that live rock rubble doesn't do a lot for denitrfication. It only really happens in bigger peices in the center of the rock where there is less flow which is ideal conditions. I was told that rubble just isn't big enough to make much of a difference. Maybe it would work in low flow areas...
