See my earlier post, mike - the one @ 9:45, just above yours - the second to last paragraph - where I mention that once a week water changes will suffice in your size of tank, with good filtration, no overcrowding, and near-adult, or adult fish. (I'm suggesting approx. 4" fish or larger). Should be no problem.
