Welcome to Canreef Stephanie! Yay another girl reefer on the board!
Bristleworms are a beneficial part of your clean up crew and really do no harm. Remove the large ones when you see them but you can cut their populations by reducing the "leftovers" when you feed! Cut your feedings and perhaps try frozen...less waste. If you can decrease their food supply they will decrease their numbers all on their own. I've had a severe overpopluation of brittlestars and found just cutting back the amount I was feeding reduced their numbers. But really...they are helping out the tank so now big worries.
