Hello,

Selling Marine pure block from my sump. This is great for reducing nitrate. It's the 8X8x4 size. It's been in the tank for close to two years. $50, first to PayPal or pick up gets it. Thanks

Hi, you don't need to replace it, it will always be there, it's like your live rock except it does so much more efficient. it nice and small and you can just put it anywhere you want. I have it in the sump.

Is it possible to break it in half? Would this work in a canister filter?

Its a very soft block, you can break it into however many piece you want easily.

The single block is the same as 50lbs of live rock.
It is super porous.
It only denitrifies in anaerobic conditions aka low flow and no oxygen. In order to achieve that with these you need the have the big (8x8x4)blocks in a low flow area. If you break it up it'll just work as normal live rock and consume ammonia and nitrite.
