I have a 66g tank that I change water in 50% once a week using the bucket brigade method. This means I carry about 4 heavy buckets of dirty water away, and 4 buckets of clean water back to the tank.
Now, if I was going to change 25% x 2 per week. It would only mean carrying 4 buckets rather than 8, twice a week.
(Ok, get a python, I know! but I have other financial commitments right now and a python that long is near 200 bucks at my lfs)
Now, the question is:
Is one water change per week better than 2 partial changes? Or just the same as one big one?
