bristle worms are great detritivors for the most part. getting rid of them is just messing with the balance your aquarium is trying to acheive. they will not overpopulate for the amount of food available.

If you feel you have a problem the best method of removal seems to be the bristleworm trap.
There are natural predators that will eat bristleworms. The arrow crab, coral banded shrimp, dottybacks, copperband butterflyfish, and many wrasses will eat them.
