I have the dart on my 8 way and some returns are split 1" outlets.Its not enough flow and my tank is 300 gal.I also have a dart for my return pump.Together it makes for a decent flow but I just bought a tunze wave box to add to the flow.I will also add 2 power heads witch I didn't want to do but I wanted more flow.
