You can upload pictures using photobucket and copying the direct link into the insert image button (the one that looks like mountains) or you can upload them directly to the site by first hitting the "go advanced" button (beside the submit reply one) then hitting the button that looks like a paper clip.

I probably didn't explain that too well haha sorry.

Your liverock should have holes, the more porous the better. It could be that there was just some gunk stuck in these holes and it is slowly washing away as the tank cycles.
