Pest / Nuisance ID (what is this?) PLEASE offer some help!!

[daveydoodle]

I think I'm loosing the battle to annoying pests or algaes in my tank. no sooner do i fix Bryopsis and GHA do I get these things. If you cannot tell by the picture I'm asking about two (2) different things. The second, third and fourth picture appears to be almost like a coccoon or white, fiberous sac with what looks like small, clear protrusions. It's about the size of a BB or slighltly larger with a hole in the center. The first picture looks like a flat white scale attached to the rock. Nothing moving on it, it looks almost like a fish scale embedded on the rock. Any ideas on what these could be?

None of those look like anything I would worry about, the spots in the first pic showed up in my tank soon after I started dosing Kalkwasser. I have the other spiny sponge things too...

I have the little white things all over the underside of my Rock and in my sump. I tried aptasia killer on them once, it did nothing... Pic 2 looks like a mushroom starting. Pic 4 looks like either a mushroom, majano, or aptasia starting to form.

I have the sponges all over the sump and frag tank. And the spots are all over just the lace rock in my tank not just on the under side some are just out lines now like something came out. I thought snail eggs cause I had a few on my glass as well

The first pic are nerite snail eggs.

The other algaes I wouldn't worry to much about it. Every new system goes through the algae phases. Just keep your husbandry up, nutrients down and export methods up to par and it will go away on its own as the tank matures.

The little fuzzy balls look like sponge.

yep, what everyone has been saying first pic is snail eggs second pic are mini fan worms and 3rd and 4th pic are pineapple sponges, all signs of a healthy system.

Thanks guys, dead on. The white sacs are definetly these (picture 1) Pineapple Sponges and the other concern is definetly (picture 2) Nerite Snail eggs. So now they're just visually unappealing rather than potentially harmful or a nuisance. I feel better. We have a GREAT collective resource here, thanks MASC!
