Just in a bucket or tupperware type container. You only dip for 10-15 minutes. I like to have 2 tupperware containers - one with the solution and one of just tank water so after I dip the coral I put it into the container of just tank water for about 5 minutes and swish it around a bit and then put it in the tank.
Edit - It is supposed to kill flatworms but I have never recieved a coral with flatworms nor (knock furiously on wooden head) had them in any of my systems so cannot vouch for this.
