It is a personal preference. Some people change 10% every week, some change 20% every two weeks, some people go for months with out a water change. It also depends what fish you have, some are more messy then others. For 300G total water volume, I would change 30G every week. If you don't want to do that much work, start with 60G every 2 weeks and see how it goes.

I suspect weekly changes can burn people out. Design your setup to have an easy draining system and top up, so which amount you decide to do its fast and efficient.

Therefore no matter how busy you become you can still do a water change.

I do a 10% WC weekly but then again, everyone is different so good luck!!

I do 20% every two weeks.

The suggestion above, of having an easy setup for doing the water change is a must... This weekend we finish the drain and fill piping... water changes should be as easy as pushing a remote to drain and another remote to fill.
