I used to fuss over my outside tubs much more than I do now, but they're really a completely different thing. Last year, I let some of my tubs go a REALLY long time before doing a waterchange. I just topped them off when they were low (for the record, my water is only moderately hard). They were still incredibly productive and didn't really look like they needed the waterchange. I DO have to frequently feed the plants, they run out of micronutrients fast. I like having some water mint in each tank for that reason. It seems to suffer from the lack of fertilizers first (by looking sad an yellow) and I can see almost an overnight difference in it when I add them back in.
