Very Weird Bristle Worm Behavior

[Walkamo]

I am a little freaked out right now. I have been having some trouble
with lots and lots of bristle worms lately (hundreds), so yesterday I
bought a couple of arrow crabs. Today I actually saw one of the crabs
eating one.. I was very happy. Well, a few hours later I was doing a
water change, and after a drained about 15 gallons I added 5 gallons of
RO Salt, and let it sit for awhile so I could measure my Salt. When I
came back to measure it, all of the bristle worms in the tank had come
out of the rocks. I mean hundreds of them were on the rock and spitting
out this white milky stuff. I have never seen or heard of this before.
I started siphoning out some of the bristle worms as well as the milky
substance as best I could. Does anyone know what this means? Is this
milky stuff dangerous? What could have caused this?#ed_op#br#ed_cl#

The tank is 46 gallons, good lighting and has been up and running for over a year....#ed_op#br#ed_cl#

#ed_op#DIV#ed_cl#Sounds kinda of freaky to me. Probably some sort of spawning thing. It sounds like you have very high nutrient problem. A few small bristle worms areOK (IMO, good for clean up)but mass hordes them indicate a problem. Give us a little more info on your system.#ed_op#/DIV#ed_cl#

Walkamo whit is your feeding routine sometimes the population will increase with
a lot of extra food wast in the system

get some other things that will eat them or even get a trap for them actually. less expensive. Definately find out the problem. mos likely cuz you are over feeding... at least to me.
