All of this started after I removed some liferock that i suspected gave me cyano, cyano is gone but i have this brown stuff now.
The initial brown stuff was hair like and I removed top layer of substrate and cleaned it and returned it to the DT, thereafter I got this diatom like stuff and it wont go away.
I have since started using diff salt but this brown stuff was there before the salt change.
