Clown, Ok sorry to post this here, but only because it was an issue with your tank.
I took my water sample to a marine biologist, he said it could be one of two things.
A. bacterial bloom
or
B. Tube worms spanwing.
Again my apologies on the Glasscages thing I was thinking maybe they used the same silicone as you did Clown.
Anyways, as an update the biologist told me to just wait it out, and I did, it is ceasing, and corals are coming back. No more strings of bacteria all over my rocks now. Just a few particles here and there.
Sorry, to post on this again, just wanted to give an update.
I'm heading to store today to buy some new filter socks, and that's pretty much it. I'm gonna let it run its course.
Cheers
D
PS I love my 9010, although I'm sure Id love a Bk much more but my 11 month old is priority over tank right now.
