Huge improvement with the new reactor.
Hooked it up this morning after removing my older GLA acrylic reactor and what an upgrade! First, the .45* elbow is a game changer compared to the old 90* elbow. My flow going into the reactor is stronger and I have more pressure building up within the reactor. It’s been about 6hrs now and it’s been awesome. With the old acrylic reactor by now I’d have a gigantic gas pocket. Right now I have a negligible gas pocket which I totally expect. But I’m guessing the larger volume and increased flow and pressure are helping a ton here. We will see how the next few days fair, but for now it’s absolutely awesome.
