Water Flow and co2 Set up
 

Hello everyone - newbie here. I have just set up a planted 55 gal. long. tank and getting ready to install a co2 system. I have a Cascade 1000 bio filter with the intake valve on the left end side of the tank near the bottom of the tank and the outtake valve on the back side of the right end of the tank using just the flow spout (not a bar). I am thinking I should put the co2 diffuser at the right side bottom of the tank for good dispersion. Is that correct? Or????? I am trying to avoid any dead pockets of water flow... Any advice would be greatly appreciated.

TIA

Outflow spout at the right side front and intake at the right side back would be the best for water flow. It would make the water circulate around the tank.
