With water changes, many people say you should do 10-25%. However, I personally only very occasionally do water changes, the skimmer takes out most of the crap you would remove with a change anyways.
When I top up my tank, I use about 2 gallons per time, and let it trickle into the tank.

although its not just removing crap- there are trace elements in fresh SW that are depleted over time- a water change will replenish these.
personally i do 10% a week via an automated system so i just open the valve from my SW store and it is pumped into the tank- a level sensor on the tank detects a rise in level and pumps waste water out to keep the tank level constant (this means some "new" water is also lost but i add more than 10% to allow for this)

RO and DI unit so i do not have to go get water every other week at the fish store. does the water store in a tank when you need it???
ok- the RO is in my "fish water cupboard" - this flows into an RO store of 200 litres.
when my RO reserve gets low under the tank more RO is pumped into it from the fish cupboard. autotop up deals with getting it up to the tank.
each week i turn on mt SW pumps- these initialy draw 60 litres from the RO store (which then opens up the RO flow to re-fill itself)
when 60 litres is achived the SW heater and circulation pumps come on (they only operate when theres 60 litres in the store.
over the next couple of days i add salt.
when i want to do a water change i use another pump to transfer water direct to the tank.....as the tank level rises a level switch detects this and dumps water to the drain. when the SW is all added all the pumps shut off and an alarm (low level switch in the SW tub) informs me its all done.
90% automated and 100% of pumps/switches hidden from sight.
only thing i really spend time on is adding salt/checking SG...rest is all just flicking switches.
