I change 1/3 every week, sometimes 40% in my "monsterfish" tanks.
but I never really get it down to 50%.

Me as well... about 25% every two weeks with very good results. My tanks are very lighly stocked (about 0.5" per gallon) and very over filtered (20x per hour... probably more like 10x with full media).

The only time i would do a 50% water change is if there was a water quality problem that i water change could fix. After we found out that it was our tap water that was causing the ammonia spikes, we went to RO water purchased from the local H2o store, and we don't have ammonia spikes now.
we found that our 100 gal had water stability issues because of very low PH and no buffering capabilities.. so we added crushed coral to bring up the PH and that problem is now solved too.
And like my hubby said already, 25% changes every other week keeps the nitrates in check and the fish don't stress so much..

I never do more than 40%. I usually do 25%-ish but perform them more frequently than once a week.
A lot depends on the stocking and filtration. Of course if you have barely any fish and high filtration, small water changes are fine. But vice versa, and you need a lot more effot.
