right you are V. they work OK but too easy for bubbles to get sucked through. If I ahd extra space one more baffle might help but I wanted as much
refugium as I could get. I'm goign to try some different drain line options and see if I get less bubbles from it since I think that is where most of them come from.
I tried tanking out the drain
PVC and going with just a longer hose deep into the
sump. Then I just ended up with siphoning in the overflow. So I cut the hose so it was just above the water line and now its loud and still have siphoning. Guess I proabably need to increase the size of the air intake on top of the durso.
