Correct. IMO The only way to get 100% of your ER's performance is through that GV mod. Otherwise, I feel like sometimes the performance is reduced.
All the riser tube/gate valve does is create back pressure which in turn cause the water/bubble level to rise in the body of the skimmer. In reality the gate valve will not increase performance. It just makes it so much easier to get it dialed in to the sweet spot you want. Prior to the mod it just skimmed too dry for me stock.
The alternate way of dialing in this skimmer to its sweet spot is by adjusting the water level in your sump along with raising or lowering your riser tube.
Trust me it is a very very simple concept once you get the skimmer and tinker with it for a few weeks.
