Newbie...What are these little creatures on my sand, and coral skeleton?

[clhardy5]

Looking at my tank this afternoon, and saw these little critters crawling on my sand, and a hammer skeleton. I've tried to search, and am thinking they may be copepods? But I'm not sure. Tried to take a video...but it's not great....but I'm hoping good enough for someone to id.



Thanks!
PS....
Tank is new (a little less than 2 months) although it was seeded with sand/live rock from an existing system
Parameters are good:
Ammonia - 0
Nitrite - 0
Nitrate - 0
Phosphate < .05 (but really hard to sell with Seachem test)
Temp 78.9
Salinity 1.025
Didn't test Calc/Alk today....but they were fine two days ago
Tank friends - Two Ocellaris Clowns, Anemone, fire shrimp - Corals: 1 zoa, 1 paly (both growing well) - assorted CUC.....all doing great.

They just look like some type of pods to me.

They're all over my glass now.....are all pods good? Or are there some I need to worry about?
