I know that once I get my tank set up, I will be able to do water changes every 3 weeks for sure (my schedule is such that I don't know for sure if I will be able to do it more often than that). I a water change once every 3 weeks enough? If not I am not sure that I can set it up. As far as I know there is no aqurium service around here.

. But you still should.
The added bonus with the minis is that it really helps (me anyway) really spend time with my tank and check everything out.
