What's this on my substrate?

[Srh444]

Hi guys,
I've noticed this brown stuff on my substrate, please see video. I have turned my light up but only a little. I have two AI lights. The blues were set on 25 but over the past couple of weeks I've turned them up to 30. Usually I syphon it out and replace with new live sand. Any ideas please?
Thanks, Steve

I can see the video if I use the app but I can’t see any algae. Can you retake the video under white lights or orange filter if you have one

Sure, I'll take some photos when the lights come on.
Many thanks

I've looked today but I think it could just be dirt or something. I can hardly see it today but have attached a photo? Taken in white light.

Very hard to see anything with that blue light on. Can you turn off the blue and leave only the white? This takes better pictures and videos.

Videos don't work on the web version of iOS devices. If you are using the app or Android, it will work. That's usually why people will ask to have the video be posted as a GIF or YT link.
