Tank has Tetras and Corys. APS test results are good. Unchanged for months.
Anyone know what it is and how I can stop it/clean it?
Thanks!

Here is the response I got from r/aquariums:
"Black hair algae. Get some Siamese Algae eaters- 3 at least. And do a damn water change with a gravel vac for the gunky brown crap- it's fungusing from overfeeding. Stop that. Your fish will not starve to death. Do several 10% water changes over the next week or so. "

Not seen anything like that before sorry. I'm sure someone else on here can pitch in with some experience though.
Best of luck with sorting it out though.
If you are talking just the brown stuff, then yes, it is just somekind of fungus from excess food remain, I had it in my tank before because I feed some food that the fishes don't like and it remains in there. So just vacuum that brown stuff out, do a water change, and cut down a LOT of feeding for 1 week. I hope it helps.
