RE: Lava Rock
Hi Jake,
There is a difference between the different size lava rock. The smaller
pieces have the benefit of greater surface area for normal denitrafication.
In this form it is most useful in corner, canister or drip filters. Larger
pieces have a larger anoxic interior area for more complete denitrification,
including the breakdown of nitrates. This is of course the principal behind
"live rock" in salt water which is used in large pieces. Lava rock is an
amazingly useful material.
Adding small pieces to your filter system makes a great media for superior
conventional denitrafication. Adding large chunks to your aquarium makes for
a great passive denitrator as well as an attractive decoration.
Best regards,
-RJ-

Is there an 'optimal size' of this? Would lava rock
'gravel' have more surface area? What I have read so
far makes it sound well worth using, wondering if
there is an optimal size?
