The walls of the aquarium were scrubbed roughly today.
This has removed most of the algae buildup that was present on the glass. The water quality after scrubbing was foggy but it wasn’t dangerous looking, mostly just lots of small algae bits clogging up the water. I’m waiting for the filter to filter out the big chunks for a few minutes before I change one of the two water filters.
All fish are doing well, with nothing else to report.
