There's over 23,000 square feet of surface area within a single block. Depends on the LR. Not all LR is equal.

There's no LR that comes close to the porousity of the Cermedia blocks.

I think a block is equivalent to something around 50-100 lbs of good LR. Just a wild guess.

Lots of good info on cermedia's website.

Depends on what you want to do.. Plates will house bacteria that consume ammonia and nitrites.

Plates can't house denitrifying bacteria. Only blocks can. Thicker = anaerobic bac in the middle = consume nitrates.
