dipping zoas

[canadianbudz604]

I bought 15 zoa frags a few weeks back and just chucked them in my tank. Now I am paying for it, nudibranches are everywhere. I took the frags out of the tank and dipped them in a RO/DI bath. One thing I didnt do was check the ph of the RO/DI water. I dipped the frags in for like 2 mins each frag. On a good note all the nudis fell off and are long dead. Now hopefully the zoa frag come back to life because I didnt just dip the 15 I bought, I dipped all 20 different types I have. None are open and none are looking too good. Looks like my first mistake in this hobby is gonna be a costly one.
