CPR overflow box siphon problem

[LuckyReefer]

i was cleaning my overflow box and the siphon tube that goes into the air lifter pump came out which stopped the siphon completely, never had this issue before if i cut off my return pump and kick it back on the siphon starts just fine but now i can’t seem to figure this out and it’s frustrating. I had it working but only from me manually starting the siphon which then the water flow was about 1/2 inch higher than it usually was and i think it was due to an air bubble being inside of the box.

I'm twitching just remembering the challenges that I had with the CPR overflow and aqualifter setup. Some people swear by it, however I was *allegedly* swearing at it. I feel your pain and I hope that you are able to work it out.

i didn’t realize without knowing but i switched the airline tubes on my airlifter pump and could not figure out why the siphon was starting man did i get frustrated knowing it was so simple lol. I just haven’t messed with the whole thing for quite sometime so i forgot.

I'm glad it was a simple fix and I hope that you continue to have good luck with it! It sounds like it might be time to add some labels!!! :)
