Flow advice. It seems I have a major dead zone in the center of my tank & random spots. I’ve adjusted the setting on my gyre I’ve added a smaller hygger (1/2) I honestly can’t figure out how to get the flow right to where it’s supposed to be. Any recommendations. Should I get rid of the gyre and replace it with the other hygger? Add a third pump? Below are pics of the pump setting and my scape with the dead areas. Would swapping the sides where the gyre is help etc TIA
