change return?

anyone know of any way to do a return system to replace the powerheads in my reef i currently have a tunze that does i belive 2200 gph and 1 seio that does 1100gph they take up a lot of room and the tunze is pretty strong flow for something that advertizes gentle currents i have it in the back blowing along the back wall anywhere else and it causes a dust storm or blows stuff over and it doesnt have a control for speed any ideas or suggestions?

 

Im sorry ollie51 I didnt understand, you want to change the return pump from 2 to 1 or the pumps that are inside the DT?

 

just trying to see if theres a way to get my powerheads out of the tank and free up the space they take up and like i said the tunze is maybe to much the tank is almost all sps but this pump is strong my tank has a built in overflow but i cant drill when its occupied

 

I have a Magdrive 18 pump that pushes 1800gph to a couple of loc-line sprayers and it works for me. I have no need for more pumps inside the tank.

 

you could use lunas idea with a device that alternates current the name it slipps my mind at this time

this is what I mean by loc-line, but instead of the circle form, straighten it out.

They are very flexible and each section can be point anywhere you want at any direction.

 

whar i would like to do is get the powerheads out of the tank and replace them with something that will give me the flow i need for my acros i move about 3500 gph now so i need to keep that amount
