Problems in new tank

[Alvi]

Greetings,

I set up a new tank in March of this year. I tried to keep it as clean as possible by using all new dry sand, dry rock, purchased saltwater, and used Fritz Turbo 900 bacteria. I also ordered ORA - Chaetomorpha Algae - Aquacultured for the refugium. I dipped all coral in Coral Rx too. However, at this time, I am getting "tube-like" things growing all over my frog spawn coral and some on the rocks. I also found these clear jelly-like organisms with small spots on the walls of my refugium (shown on the toothpick). Can anyone address what these pests are and how do I get rid of them? Thank you.

The first two pics are vermetid snails (nasty pests) and you can crush them all the way to the bottom of the base or put superglue at the tube opening. For the third pic, I’m not sure, but it looks like some kind of a flatworm?

Thanks for your help! It's really a shame to get all of this with all the precautions that I took this time around with the new tank.
