Using a whisper filter is fine. Honestly I think he filter causing stress thing is a little overblown. I use two HOB filters with my ACF. I think with ADF you would want a more gentle filter mostly for the fact a current may make it difficult for them to surface for air since theyre not the strongest swimmers
So yes a whisper is fine, I use one myself.
