The best thing I did was move to a new house with an unfinished basement! I then built the basement with a fish tank in mind. Still could use more room though. With my new tank I'll definitely need long feeding tweezers and an expendable feeding "baster" thing.
I also built my own stand so I made sure it was enclosed with multiple doors to access everything. I used to run 2 tanks and that was quite time consuming. I can't imaging any more than that!
