live rock question
i recently started a new 150 gallon tank. i mixed my red sea salt and loowley added through the return in the sump. i have a refrugium set up in the center chamber, it has sand and live rock, well I looked today and see the live rock is covered in white, the same white stuff I had to scrape off the glass, did it kill my live rock or is it going to be ok, do i need to replace the live rock, do I leave it alone or do i clean it... not sure what to do
thanks
Ross
