The reason this happened was because my rodi filters were faulty and leeching tap water. It took a while for me to troubleshoot it. I then made the mistake of overdosing the tank with vodka.

The RODI is 0tds. I put phosban and carbon and running skimmer with 2 filter socks. And I got a big water change.

will this mess clear up without me needing to manually scrub?

what is this brown gunk called?
