Killing Aptasia or Sterilizing Rock

[monocus]

i find the berghia work the best-but you will never really be free of aptasia.after my move i put my live rock out in the elements for 6 months while i was rebuilding my fish room,after 5 months of my 220 running again-i have aptasia from my old rock.it will go in cycles-berghia will eat the aptasia then starve(loan them out)then the aptasia will grow back.the bonus is that you can sell the new berghia.i didn't have to pay for anything for 7 months while i was doing that at my lfs
