I routinely test every week for ammonia, nitrite, nitrate and Ph and do a water change every week. Monthly is not enough imho. I also test more regularly if I've added new fish, one looks poorly or off colour or done the monthly maintenance on the filters - just to be sure.
Weekly tests seems like overkill. Unless something bad happened to your filter or something died, I dont see any point in doing ammonia and nitrite. Weekly water changes are always good though
