Well to be honest nothing..but I learned my lesson. When I wanted to get into sps's my local supplier gave me the basics in sps keeping. I added a few frags and in s short amount of time lost them all. I later found out that I had AEFW. I have since then setup a Quarintine tank.
I do feel safe because the frags I'm getting now are coming from a R.C. member that has never had a AEFW issue.
Just want to make sure if I wait another 20-30 days so 50-60 total and there are no signs of those little f*#*ers I'm good to add a few more frags
Thanks
but you see how u are doing everything same as before right ?
so what makes u think u wont get AEFW this time around ?
did you QT those frags ? dip them ?
how about new frags ? will they go right in ? or QT ?
not judging, just saying if you are using no protection, waiting wont help neither.
if u want to be AEFW free, set up a proper QT tank, dip new corals, and put them in QT for a month, dipping weekly ... you will be sure to kill all eggs this way as well, before introduction to main tank..
or do what I do , and just pray, and add the piece to ure main tank, but u dont get to worry about AEW this way

lol I have them...
