More water movement?

[jond]

I am currently running 2 6101s with a multicontroller on my 280 (72X30X30). I have some dead spots in the back and bottom sides. My return is only about 1,000 gph as I want slow flow in the sump. I currently run the streams on interval 2 at 100/30 %.

My question is how to best get more flow. Should I try a different setting on the controller? Add another stream? Add flow accelerators to the returns? Or any combination of the above or any other suggestions welcome.

Thanks
