Massive Bristle Worm Kill 3/15/11
Hi I just spent the afternoon cleaning my 58 gallon tank and doing a
ten gallon water change. I do the same cleaning every other week.
However this time I also used my de filter with the gravel vac
attachment to clean some algae scraps and small bristle worms ( my wife
hates them!!!) from the substrate.
It has been about 1 hour since I finished my cleaning.
All OF A SUDDEN !!! the worms are coming out from everywhere and
Worms up to 1-2 inches and maybe 50 or more very small ones are just
dead all over the place.
So far the fish, 2 Banggai cardinals, a royal Gramma, an ocellaris
clown, and lots of mushrooms all seem fine.
The tank has been up and running for about 2years, water changes are
all done with ro water. and all tests seem fine.
temp 75, ph 8.2, salt 1.023, nitrate 0, and phos .25. I am using
swimming pool de powder which I have used a few times before. I am
somehow suspecting that a bit of powder got in the tank and had some
adverse effect on the worms. Any Ideas??
<Likely either the DE powder (silicate) or more probable, a chemical
cascade effect from the removal/death of the algae. Yes, some chemicals
from these are VERY toxic, and selective (not affecting other life
Thanks in Advance

Dying Fireworms - 6/11/10
I have a 150 gallon reef aquarium which until recently had a very large
population of Fireworms. I chalked the abundance of worms on the fact
that I feed my sun corals very regularly and the worms took care of the
leftover Mysis shrimp.
<A likely scenario>
Over the last few days I have started to notice dead or near dead worms
showing up. Today alone I removed 7 of them. Any ideas ?
<As to cause? What else, new have you done recently? Supplements,
Nitrates are 10, salinity 1.023, ph 8.3, calcium 425, temp 80.
<None of these is at play here... Bob Fenner>
Dead Bristleworm 5/30/07 Hi I am a new marine aquarist,
<Hello> I bought some live rock that I later discovered is alive
with bristleworms. <Common.> I have read that most are
safe… I can't identify if what I have is safe breed so have
removed the rock from the tank & have it in a salt water filled tub
& have been trying to capture them with tweezers & wiggle them
out of there holes - but on occasion they have torn in 2 with the
latter part retracting into the hole. <Almost impossible to catch
them all. Not worth the effort either.> Q: Do they regenerate a head
or will they die within the rock? <Most likely die.> Q: If they
die how long should I wait before I move the rock back into my tank?
<I would not worry about the worms, chances of getting any that are
harmful are pretty slim.> Cheers
