How important is flow - for plants and fish?
I have a 90P running an Eheim 2217 and an Eheim Skim350 (small powerhead). It's pretty strong because I'm using the nozzle, not the spraybar. But it's not the speed of the flow I'm concerned about, it's the placement and volume that I could use more of as my tank still has a 20-30% deadspot.
How important is flow to the health of plants and fish? I'm running high-tech, heavily planted.
