Sudden white spots

[torresj36]

I came home from work today and found all of these white spots on my snails and some on the glass. These were not here during yesterday's inspection. Please help. I tried blowing them off with a baster but they are on the shell. Water tested yesterday, parameters below.

Temp 78
Phosphate 0
Nitrate 0
Salinity 35

Looks like Spirorbid Worms and no need to worry.

Bluprntguy, thanks for the quick response and i.d. just read about them. Probably always had them to a degree. Once again, thanks for the info and sharing the link.
