Heres the story, I have a 20g long that has 30 lb live rock, and lots of corals, mostly softies and a few brains. This tank is infested with flatworms and "zoo eating" nudibranch, and this sucks.I want to transfer all my stuff from the 20 over to a 37gallon tank already set up with LR and sand, and I dont want any friggin bad critters in the new tank (flatworms or zoo eaters). Should I
1) fresh water dip all corals and live rock (zoo's, shrooms, open & closed brains, ricordia)
2) shake everything like crazy under water and hope to knock off everything
3)use "flat worm exit" chemical, and then transfer everything before the water gets too toxic from the worm deaths.

let me know what you all think. Thanks for reading.
