Hiya, I never had a problem again after I dealt with it in my nano tank. I would break down the tank and remove as many as possible the same way I did, but if you have a fair few then maybe getting new substrate might be better. Be careful though because they can sting!
I'm having a freshwater bristleworm infestation as you did! Was wondering if yours came back after you manually removed them?
