Hi Guys,

just noted there are these brown hair strands stuff on my corals and I'm struggling to find out the cause and ways to remove it? what are some ways/methods to solve this?

Been constantly doing weekly water changes and dosing minerals to supplement the coral growth as well.

Can you get a pic under normal day/white light?

The most likely is green hair algae, but hard to tell from those pics.

What water changes have you been doing? Small changes will do very little to control nutrients. You need large changes, fairly close together to make a real difference, and to also control the issue creating high nutrients in the first place, so it doesn't build back up.
