Filtration by plants or mechanical means does little to keep the water clear of pollutants. The large, frequent water change does most of the job.

One positive effect of plants is removal of nitrates and ammonia. If your tank is getting phosphates from fish food, or otherwise, plants remove that too. Otherwise I agree.
