ellisz: I believe the theory is that the bio-balls break things down to the nitrate level and leaves the nitrates to float through the water column. Whereas LR
all the different bacterial colonies are coexisting so when the water is removed of the nitrites and replaced with nitrates its passed to the next set of bacteria which removes teh nitrates. So with the LR
, they're be removing nitrates, but the bio-balls will remove the nitrites, but leave the nitrates in the water column. Thats why folks don't "suppliment" LR
Lawdawg: if you're considering corals etc, then start now. use LR
this way you won't have to worry about trying to transition your system from BBs to LR
. the LR
are mostly maintenance free.
