junk on the glass

I added a bottle of tigerpods last week, and lately I have been seeing these spots on my glass that kinda look green coraline spots. There semi-transparent, and kind of have a spot in the center but dont appear to be moving at all. I have been cleaning the front glass maybe every 2-3 days but these things dont come off with a normal scrubber brush. Theres alot more of these spots on the back and sides than the front.

any ideas while I try to get a decent pic? could it be flat worms, copepod eggs or new algae?

Red circles = unknown
purple circles = coraline
black bar = #2 pencil

Hard to tell by the pics, but by the shape I want to say coralline. Is it hard to scrape off?

 

There very very hard to scrape off with my brush. they do come off eventually, but I wanted to make sure i wasn't committing genocide on my future pod population before I did so. I never noticed these spots until recently and the only thing I did differently was add in a bottle of pods, and a few corals.

Looks like coraline spots

 

Just green coraline. I get it off with a razor blade.

 

a razor blade would make a mess of things in a hurry on an acrylic tank . . . i'll just get to scrubbing when I get home.

I don't know what your spots are. However, I do know they aren't pod eggs
