little white dots all over!

i have hundreds maybe even thousand little tiny white dots that stick to my glass. they are a little white dot with a few little "legs" that attach to the glass....overflow etc. i use my mag float to clear the front but an hour later it is back. i have copepods and the only thing i can think is copepod eggs?

 

sounds like hydroids they are a harmless form of jellyfish i believe

 

copepods would be my guess, i have never seen thousands of hydroids before

 

ok i looked up images on google it is hydroids. man they really pokedot up my glass i scrape em and they come right back. i think my snails eat em off the glass but it doesnt seem anything to worry about
