red clay bricks and Fe leaching

["Kinney, Travis" <kinney at pdtarchs_com>]

For you chemist types;

I was thinking of tying riccia to some red clay brick pieces I have. Do you
think the red bricks might actually work well in an aquarium because they
could add to the Fe in the water column? Or do you think they would be
pretty much inert?
