Reminds me of...my tank!

90s are a nice shape.
if I were you I wouldn't use that old sandbed, I'd toss it and start fresh. Keep a few cups of it if you want (if it has been in a running tank this whole time). An old sandbed dies really quickly in a bucket, and you're introducing a bunch of dead crap into your new tank. Some people manage to get away with it, but I wouldn't risk it.
