LOL! I'm asked that quite a bit from this picture. Yeah, the pump's turned off and I have siphon breaks just below the water line in my return pvc lines. Luckily this is as high as it goes. When it's running, it's just above the baffles and there's a very small waterfall going into the return area. Not enough to make bubbles, just enough to get the refugium part moving some.
I appreciate the question, though and it's definitely not out of the realm of possibilities that I could've screwed it up. I've made plenty of mistakes.
Best regards,
Tom
