I noticed something on my glass today. It looks like very little white starfish. There is also some white specs floating in the water. Any ideas? Are they good or bad, if bad, how do I take care of it.
The tank at ich about 2 weeks ago, there are no fish in the tank. Just LR and a couple corals and a CB shrimp, and cleaning crew

Hydroi Jellyfish it is. from what i read these are nothing to worry about. I am going to use the magfloat to scrape them off the glass. Is there anything else I need to do for these.
Thanks for the help. In being new to this hobby it is nice to find a place for quick help.
