I am in the process of doing the 6 weeks of pulling and dipping. I just performed my 2nd dip yesterday. My first dip, last week, didn't go so well. I had two fully encrusted acros on a piece of flat shelf rock that I didn't want to remove the acros from. The shelf rock and acros fit into a 5 gallon bucket so I dipped it without removing the acros. The shelf rock was very porous and apparently I didn't rinse it well because the next day my cleaner shrimp was dead and my pod population was non existent. So yesterday I removed the encrusted acros and tossed the piece of shelf rock they were on, which I should have done the first time. On a good note I have yet to see a flat worm. I do believe I will come out AEFW free at the end of this.
