I was thinking more of keeping the 1st sock and the 2nd use some kind of media. I feel you still need to catch junk in the 1st. Just wondering if anyone is doing this at all.
Which grazers are reef safe? I kinda reluctant to get more fish or inverts that do a 180 and start munching on things that they were not supposed to be munching on.
Once in awhile I'll scrape these off of the bottom of the zoa frags. I notice today that my sump is full of them. What are they and how do I get rid of them if not tank friendly?
