Anyone else have an issue with air in the lines? I noticed that I had a ton of air in each of the lines on the outgoing ends of each pump, but none in the incoming side. I pushed each line firmly onto the pump and made sure it was tightened down really well, then primed each pum again to get all the air out, and within a couple days it looks like this again. It was the same thing it’s the colored Red Sea tubing as well, but you just can’t see the air bubbles since they aren’t opaque. Not sure how to solve this…
