what is about to hatch in my tank(!) ??

Not sure if I want these to hatch in my reef tank(??)
they are clear sacks with white [eggs perhaps?] enclosed and attached to glass and filter intake. To view them with naked eye they just look like little white spots however, once we shot them macro and viewd on the computer- I am not sure what we have here-

setup=
125 gal
usa current orbit (2x250 mh, 4 vho actinic, + moon lighting)
Chiller
wavemaker
4 powerheads
Protein skimmer
filtration = 800 gph

1- beginner coral (smile)

 

Some kind of snail or nudibranch...
Nudi eggs

 

I would say snails if you dont have nudis in there already.

 

nudi's came hitchhike their way into any tank via any new coral or liverock, same goes for any kind of hitchhiker and/or parasite. Just because you didnt add a fish doesnt mean that nice coral you bought didnt come with ich eggs on it.

 

ive never seen snail eggs like those. they look similar to nudibranch eggs.

 

See post, nudi's,nudi's, nudi's

Look about same to me...:-/
