Bubble Magus Doser Issue

[clowndude]

I setup my new bubble magus doser today per the instructions and purged the lines like it says to do. My problem I'm noticing is that my pumps run every hour, but in between the time I notice the fluid that is drawn up in the intake slowly goes back into the bottles. So the problem is when the pumps kick on it just sucks the liquid up a few inches. This is causing it to draw air into the pump. I checked the lines on the intake side and bubble magus bottle side.

Any help would be greatly appreciated.

must be getting air in the line somewhere, try using a zip tie to secure it to the pump.
