Hello I have a 90 gallon planted tank with CO2 injection, the co2 infused water comes in on one side of the tank. I think that the side of the tank with the co2 water comming in grows better than the other side. There is a decent but not a huge amount of circulation form the over flow filter in the middle of the tank pointed away from the c02 inflow, and the overflow is right by the co2 inflow. Now I am just about to start a 350 gallon tank with non overflow filtration and I am trying to figure out if I need to split the co2 infused water inflow to 2 side of the tank to prevent uneven co2 distribution. This tank has 2 of the large eheim filters.
