What is the White Stick Web Like Stuff Above the Water?

[BadObsession]

I am doing quarantine on live rocks to get rid of unwanted hitchikers. Placed it in a large plastic container with salt water, but after 2 days, there is this white sticky stuff that looks like webbings on top of the water. I changed the water, and soon after(though not as much) - same thing.

Just curious and trying to learn more.

MANY THANKS!

Please post pics or videos of the substance you mention. Can be Vermetid snail, mucus from corals as examples

Here. It is all over the water surface. I thought it could be from die-offs? Especially since the first few days, the water/rocks became very stinky.
