Bah....
 

So after a hectic 3 weeks of work related issues and attending a safety conference I finally had a chance last night to do some maintenance on my tank and in my absence I had some unwelcome visitors reappear in the form of purple clove polyps and instead of one rock they are now on six rocks on at all levels of my tank so unfortunately I can't take them out and not ready to nuke my tank so I guess I have to learn to live with these annoying lil buggers....oh the joys of tank ownership

Find a fluke tab somewhere :)
