That makes sense to me.
It would seem to me an undersized system should still be of some benefit, just not full benefit.
Just like wind can aereate a pond, if it takes a sustained 10 mph wind to do so fully, it seems a 5 mph wind is better than no wind at all.
Thus logic would imply an undersized system would still be better than no aeration at all.
But I thought I might be missing something. Like maybe partial turnover might encourage unwanted algae growth or something other weird going on.
