I have the G4+ with the Sedra 9000 pump. Recently I purchased the Gate Mod materials from asmskimmers.com. Now that I have installed it I notice that a decent amount of bubbles is being forced though the output of the gate mod into the sump. Before the gate mod I had close to zero bubbles existing my skimmer. I am worried that I am not skimming as efficiently now and now I have to deal with bubbles returning to the tank. Any suggestions?
