Is this dinoflagellates that is bothering my bird's nest coral? They come out when light is on.
I thought dino is on sand first. My sand is clean (maybe the sand sifter is working to hard.)

I hate photobucket.

Pictures work fine for me.. (I do use a photobucket fix extention for chrome)
And if they haven't fixed that one yet I fixed all the images on page 2 a while back

Ha, I didn't know when photobucket is blocking the pics, there is a way to go around it.
"Photobucket Hotlink Fix" extension works!

Glad I asked and thank you for the reply. Now browsing on reefcentral is a lot more fun.

Could be dinos but the only true way to identify is with a microscope. You can get them on amazon for $15. Anything else is just a guess. FYI depending on the species they will eithe hug the sand or go into the water column as they are light sensitive

Looks a lot like Dinos. Use a baster to blast them clean. Start running carbon as they put something poisonous into the water. Mine cleared out with a UV sterilizer but it has to be a good one like those BRS sells. 1 watt per 2 gallons.
