Can anyone help me ID what this brown stuff is?

I just did a water change yesterday and noticed this crazy brown bloom today. I make my own water and my DI is almost exhausted. TDS is still 0 I believe

it doesn’t really blow off when I turkey baste it...not sure if it’s brown cyano or something else?

Change di for sure. 0 tds doesn’t mean it’s ok. I can be releasing ammonia and silica etc...

Anything I can do to clear it out in the meantime?

@Coral reefer is right. Change out media immediately and just wait. It’ll fix itself over the next few months of water changes and proper top offs.

You could try brushing or siphoning
