I plugged in a 200gph and now it is working as it is supposed to. Much better flow and no "almost lock ups" at the end of the day.

What I have been wondering is that I got the powerhead at the left of the tank and the output from the reactor is on the left too.

Should I extend the output of the reactor to the right to create a sort of flow path?
Would there be any difference in CO2 distibution in the tank?
