Behold the part that I don't understand......
How does the flowrate have anything to do with how fast water falls? Gravity is constant.
If I run my wet dry with a 1K GPH pump then the water still falls through the bio tower at the same rate as if I was pumping 4K. The difference is the water actually makes it out to the perimeter of the drip plate with 4K as opposed to only an "island" of the drip plate with 1K.
IF you did NOT have a drip plate this might hold true..... But most "trickle" filters do use a drip tray now don't they?
