so apparently I mixed up my waste water container with my water change container for a total of two water changes, one each week and I think the cause of it is this little issue. My tank water smells a bit funny, did a 25% water change to hopefully balance out the 20% I screwed up. I use a turtle clean 318 filter in my nano to serve as a safe and effective power head for circulation, I clean it once a month on average but man did that thing had some gunk I neglected the last week and I just cleaned it so hopefully my cyno goes Away. It’s hard stuck to every surface and I can’t vacuum it so I added some codium as a counter measure
