I bought 100lbs of live rock from a fellow reefer covered in aiptasia and loaded w/bristle worms (some too intimdating to pull out with tweezers). I tried keeping the LR alive, but messed up by putting it all in a small trash bin with saltwater. I let it set for a week without a powerhead and heater, everything ended up dying because of the high ammonia spike. I figured it was ok since I didn't want the pests, so I dumped the nasty water, rinsed with fresh water, scrubbed with a brush, then soaked in saltwater with high salinity for 30 minutes (more worms came out). Then I allowed to soak with normal saltwater for another week. Things kept dying...but I kept rinsing with fresh water, scrubbed with brush and soak with new saltwater. I did this for 2 weeks, now the smell is gone and so far no aiptasia or bristleworms. My only regret was the other stuff that was living on the rock, sponges, pods and othe bacteria, but it was a good trade off. I plan on buying some peppermint shrimp, and clean up crew to take care of the dead stuff on the rock and to maintain it too.
