Sk8r said:Thing about bristleworms is --- if you have 'too many,' this is the very tank that shouldn't get rid of them. They reproduce according to the food supply, so if you're seeing too many bristleworms, your tank has too much nutrient---take them out, and that nutrient overload can bring your system to a really bad place. What you need to do is clean up the water and get the nutrient down and the population will die back. This is true of many 'blooms' of weird stuff.
