What is this and is it good or bad

[mike_dani]

OK NEWB here and I something new to the reef......

I don't know what it is other than its white doesn't move and looks to have feathers of a feather duster on it, it is in the middle of this picture and a few around it.

Thanks in advance for your help.

YEY the tank is only six weeks old and I am pushing the limits by adding 2 -3 fish a week.

I am checking the water daily and have a backup tank just in case just trying the live rock, live sand, and cycled water theory.

If yuo dont cycle your tank properly you will never meet that biodiversity a tank should have.

+1 the bad stuff happens very quickly! everythinglooks great and the next day it's a foul soupy mess

 

[blinddog]

That is the truth I have seen it happen not my tank

It's hard to resist, but listen to the collective experience of everyone on here...slow down. I'm fortunate to have never had enough money to go fast

+1 on slowing down and does anyone know how to get rid of them? I have a good bunch of them and I know they dont really hurt but would like them cleaned up because they are multiplying like wildfire.
