#ed_op#DIV#ed_cl#I have a white fuzzy looking algae growing on my live rock. It grows on top of the brown algae growing in a couple spots on my live rock. Does anyone know what this is, and is it harmfull. Water tests good, use only RODI water and change 10% every couple of weeks. Took a couple of pictures but it doesn't show up well. Like I said only shows up on the brown algae and another question, what is a good critter to go after the brown algae. I have lots of snails, blue leg and red leg crabs although probally need more. Thanks for your help!!!#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#IMG alt="image file name: 2k82c7c95752.jpg" src="http://www.captivereefing.com/richedit/upload/2k82c7c95752.jpg" border=0#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl#
