It entirely depends on your nutrients in the tank. There are nano tanks that do almost 100% water changes without any issues. If you have a lot of excessive nutrients than you might need the 20% weekly. Some don't do water changes at all.Is there such a thing as too much regular water change?

I do a 20% every month. I used to do it every week. Soon as I went to every month my tank has started to thrive!
