So I've been constantly tweaking the flow patterns in my tank trying to not have sandstorms or dead spots.

I have an MJ1200 for my return pump pointing with the output directed along the surface of the tank

about 3/4 of the way down the back wall (directly under the MJ1200 output) I have a Koralia 1 pointed towards the top front center of the tank

on the opposite side of the tank I have my Koralia Nano on the side glass (3/4 of the way down) blowing towards my rocks

I'm thinking my K1 is fine where it's at but I think I need to upgrade my K Nano to something with more oomph (it worked fine in my 8G BC but I think this tanks too big)

So I've been trying to figure out what to get...

Another K1? a K2? A Tunze Nanostream? Vortech MP10?

Anyone have any thoughts, suggestions etc?

I can get a FTS tonight so you can see where my pumps are actually placed if it'll help....
