It seems pretty porous so I think if anything, it will be good as a decorative rock?
Even if it doesn't harbor all the bacteria like live rock does, surely it will eventually get a good coating of coralline etc.. and blend in?
I don't so much need it to actually be live rock, just something that will eventually look like it, a good way to boost up my rock amount and fill out my tank.
I already have enough live rock as recommended (1lb/gal
) for biological filtration, this is just purely to fill open spaces etc...
