Stream position again

[IanJ]

Hello
My tank is 5ft x 2 1/4 x 2

I have a Iwaki MD55 return pump(feeding chiller as well) which i assume pumps back some 3000 lit/hr or so right to left, towards the front glass.
I have a Ehiem 1060 on the bottom, left back corner with the flow across the bottom towards the overflow in the right back corner.
I have a Stream 6080 which is in the back right corner, with flow in the same direction as the return. A stream TS12 is in the left back corner pulsing 30%/100% aimed towards the front middle glass.
I just can't seem to get the right balance of flow/current that i look for, it tends to be too turbulent or dead spots.
How would you arrange things?

I can't say because I wouldn't really no the other pumps interactions and I would probably eliminate the 1060 if it were me. Good pump but I don't think you need it and it is a high pressure flow and adds a lot of heat. I would probably keep the MD55, sounds like it is on a Seaswirl. Keep the 6100 running but maybe direct it to the opposite corner instead of the center. Then do the same with the 6080 from the otherside but only run it every other hour to create a surge to stir up things.

Thanks for the reply.
It is a bit of a mis-match of pumps. I use the 1060 to blast across the bare bottom to the 1262 that sits opposite that feeds the skimmer, idea is to push as much dirt in the direction of the skimmer. Heat is a big issue.
MD55 is the main return pump and exits through a fixed outlet.

For the 6080, when you say run it every other hour, can it be run for say 15 mins on 30min off, or is a 1hr off period a must?

I guess the long term solution would be to remove the 1060 and change the 6080 to a TS7

A 1hr on period is a must, it could be turned off briefly.

Ok, thanks
I have removed the 1060 and will run with just the 2 streams and see how it looks over the next days
