They reckon once a week drain 1/3 to keep it pristine? Tie that in with good pH, filtration etc and you should be winning ..

Do you even need to take the fish out if you're not cleaning the entire thing?

In terms of cleaning the entire tank, once every 6 months, if that - depending on what kind of tank you intend on keeping and how many/messy your fish are. That's why you want to invest in the best filtration you can.
