Any idea?

My coral has stringy this coming off it? Not from the polyps though?

All parameters are in check,

Hard to tell from the pic

Could be slime. What's the color or the strings

If it is coming from the polyps (some of the lower ones one the pic do) most likely sweepers.

I moved it up yesterday . Never saw it do it before.

Probably sliming up from light stress. Keep an eye on it to see if it starts to bleach, but this is a normal response. The slime helps block some of the light and removes things irritating the coral. If it gets worse, just move it lower or shade it and do a slow acclamation to the higher light levels.

If you see brown slime, that's the coral expelling zooxanthelae and is in the process of bleaching. As long as it's clear, things should be ok. Just observe it for now.

Mesenterial filaments. Used by coral as both a feeding mechanism and defensive mechanism.

That was my other guess, but he said it wasn't coming from the polyps which pushed me towards just slime
