I recently added some lr
to my 77gal. Its in the process of cycling now. But i have been noticing somthing on part of one of the rocks. I just read this:
"After live rock has been added to an aquarium, keep an eye out for any white filmy or black areas on the rock and remove them. These are dead or dying organisms and can quickly pollute your water if not removed. "
And thats what it looks like, a filmy substance. Anyone know what this is and weather i should remove it or leave it. See attatched pictures. (sorry for the size but i needed to keep the quality up)
