These pieces of rock have been in a bleach bath of 4:1 for two weeks and they are still visible and attached to the rock....
Back they go into another bleach bath

No it is green/brown palys
Pulled rock out of my tank and bleached them but I think my math was off tote bigger than I thought so bleach was only 10 : 1
