Interesting. Ok--I'll remember the "no question is a dumb question" rule
Also--what about using those zip ties to secure the gutter guard or whatever else?
Side note: I've always had a bit of an issue with microbubbles (I use it as HOB) and the bubble diffuser box was always noisy. Well, I put some airline tubing on the output vent hole and the other end about an inch below the water surface. Ta-da! No more microbubbles or noise (for now). We'll see if it continues to work
