Slimy stringy

[JDR0505]

Can anyone explain what this stuff on my rocks is? Slimy and stringy, I'll do a water change and clean glass and rock and when everything settles its right back on my rocks driving me crazy.

We can't see it. Set your lights to all white or use a bright flashlight to light up the area and wash out the blue.
Having said that, I do see a feather duster or aiptasia in there.
As for what you're seeing, without a better picture, my guess will be sponges.
Is this a new(ish) tank? Sponges are very common and harmless but do look strange if you've never seen them before, especially when they pop up all over the place.
