Of course, Dave working extensively with pumps and water at depths and temps and DO2 all those are considered. The post would be pages long to explain all the details we consider. The wide range with a given pump is dependent on a limited range of microbe acivity, not on the water volume. That was my point. Water depth and pump sensitivity to back pressure is considered. Many hundreds of hours testing are involved in "jumping" to the conclusions I submitted. Bob.
