Does anybody have any experience with these unsightly tube worms that send out cobwebs all over my corals and rock. They have spread in every corner of my 180g bow front reef tank. They have even grown on the return nozzles and powerheads. They have even grown on some Turbo Snails. I'm almost deciding to break down the whole tank get rid of all rock and everything that has a worm on it and start all over with all new rock. To describe them; they look like small appendiges growing through everything, about 1/8" X 1" to 1-1/2" long, very hard and sharp. Everytime there's a disturbance in the tank they send out all these cobwebs disgusting!!. Please help, if anybody knows of some method to get rid of them, let me know. Thanks.
