Man that sucks to hear.
Good luck with re-homing your fish as well as keeping your favorites. Maybe something like a carbon filter on your tap would be enough to keep up with water changes at the new smaller scale, after downsizing.
Thanks. I've actually started putting filter socks filled with carbon back into my power filters. For years I didn't use it unless I needed to pull medication out of the water but now it seems to be worth a shot. It does at least pull the color out of the water after a few days. Maybe I need to set up some storage barrels and age the water with a carbon filter for a few days and see if that improves anything. It's still a lot of water to store considering my tanks are mostly 150s now.
