Hi guys,
got some live rock which smelled bad, so decided to cure it in a separate container.. Decided to try something new by adding some bacteria to 'speed' up the process. Next day, the rock was sitting in black water(oily scrum layer on top & man, it stank!).
I did a 100% water change & even gave the rock a scrub today with toothbrush, but the rock is still black.
No visible die off, no sponges, etc, the entire rock is just black, looked like it was dipped in ink...
Any of you guys experienced this before?
