That's not actually entirely correct. In an emergency situation, yes a single large percentage water change will be far more effective then the same percentage being changed by smaller multiple changes. But when these two identical percentages are changed over a bi weekly, monthly, etc. period of time the difference of both removal and additions is very very small. A few percent, to points of a percent. So one could argue this is less effective, but the difference is literally so small that it's nearly irrelevant.
Switching to a dialy water change schedule has made my workload easier for me to maintain. Doing my daiky change takes 15-30 seconds and I am done. The same amount of time it takes me to peak into my sump room and make sure everything is running and working. I no longer need to heat the water, I can mix a month or two and store it, at anytime that is convenient for me, not a given day deligated by my water change schedule. Never mind reducing potential stressors on the system by doing larger percent water changes. To me this works best for my schedule. But I certianky wouldn't say its a fit fr everyone.
