I think it was back around the 9-11 events that South African researchers happened to notice that solar radiation received at ground level increased by around 10% during the grounding of airline fleets world wide. If I remember correctly, this led to a measurable increase in plant growth over...
Thanks for your prompt reply. You make some good points about the variability of individual filter performance, but it would be hard to measure and control flow rates etc without, as you point out, extra bits 'n pieces. A larger filter would be the logical solution, but I'm really restricted by...
I know that this was an old discussion, but in case anyone is around, I am looking at putting three in-line domestic water filters in parallel, to increase the flow rate without significantly affecting the filtration. I recall from studies many moons ago that fluid flows through such splitters...
