Cermedia - marinepure blocks

MarinePureâ„¢ Technical Information

Who is using this product? Can it be used in place of live rock in a frag tank scenario? If so what is the ratio of blocks to pounds of live rock?

 

[Usctom]

I have 2 quarts of the spheres in my sump. I also have live rock though. On the Dr fosters and smith website it say 2 quarts is good for 250 gallons. I have a hard time believing that.

Ya I see the marinepure website says one block 8*8*4 is good up to 200 gallons. Thats what I am trying to figure out.

Anyone else use this product and have any insight or feed back?

I am planning on putting one of those big blocks in my sump. They're used at the Aquarium of Niagara and they have a crap load of those big blocks in their system. I'm building a 120gal and have about 100lbs of dry rock and will put just 1 big block in.
