If you are using a filter other than a UGF (under gravel filter) then you shouldnt have to worry about the bacteria so Id only keep like 5ish gallons. BUT if the water out of your tap is way different IE: Tap water ph 6 and tank water ph 8 then I would keep more of the water and do a couple smaller water changes.
no ugf.....just a penguin biowheel. tap water is pretty stable once the chlorine is removed. ph 7

as long as your tap water is very close to your tank water, then you can easily change 50-75% of the water.
