Bubble in Overflow

I have a large bubble in my Lifereef overflow tube. I don't know if this normal or I should try and get it out.

Try speeding up water flow through the U-Tube by lowering the inside box. It could build up enough to break the siphon and then you will have issue. The down side is that you will have more flow to your sump if you have a power outage so also make sure you have room in your sump to handle that.

You need more flow. You dont need a ton. Maybe 200 GPH or so.
