ID.. White dots on my lr and glass (pics)

[mike27t]

Hey everyone, I havnt scrubbed the right side of my tank for about 2 weeks. As I was about to clean it today I noticed these little white dots, some on the glass and some on the LR. They are about 1mm in size and are round. The white dots are only on the far right side of the tank where it has the least flow. About 50 of them on the glass and a lot more on one of my rocks.
Tank is about 3 months old
Params
Ph 8.2
Amm 0
Nitrite 0
Nitrate 15-20
Calc 460
SG 1.025
Any ideas they are?

Thanks for looking and for any suggestions.

sand grains?

the pictures make a definaite ID nearly impossible but try looking up, q-tip sponge, and spirorbid worm, and compare them to what you see in your tank.

might be baby snails? you have any snails in your tank? was that picture taken at night? at night my glass looks like that.....even sometimes in the morning, i'll have a couple still on there....

Spirorbid Worms they are nothing to wory about..they are like mini feather dusters..I have had them in every tank i had. they dont pose any harm
