Is anyone able to ID this?

It’s easier to see under blue than white lights. It looks like clear/whitish hairs or mucus that appeared exclusively on the underside of my hardscape. It seemed to pop up in a few locations very quickly but hasn’t spread much at all since it first appeared. Any help is appreciated.

Are you carbon dosing?

No, I’ve never done it before. Is it something I should look into here?

No. Sometimes you get bacterial growth dosing carbon.
Are you dosing anything like Microbactor7 or other bacterial in a bottle products?

Nope, Fritz and arag-alive to start around a year ago for this tank and no bacteria since. The tank has a really healthy micro fauna population and never much nuisance algae to deal with other than a little in the sump but just manually remove that along with my chaeto. I do a 20 percent water change weekly like clockwork and am running around 8ppm nitrate and 0.09 phosphate. Whatever this is that’s growing doesn’t seem to be hurting any chemistry so I haven’t been too worried about it but just thought I would post to see if anyone thought it looked like a problem

Looks like a healthy tank.
It's just odd to me that it's growing in a shaded area.
Hopefully someone can provide a better ID.
