Dosing pump issue

Just came home from work and I heard my dosing pump running 4 hours after it should have been. It dumped 2 weeks worth of 2 part calcium. I took a quick test and got 670 any thoughts would be appreciated thanks

On the siphon back issue. If you turn the cartridge 90 degrees so it faces forward instead of left or right it might help. On the over dose do a normal water change, then let it sit and it will drop naturally.
Can you post your code?

Well I replaced the small tube but it still won't pull the fluid from the container without assistance, and it still drained back once I get it pulled through.

sounds like the dosing pump head is mis-aligned. if the rollers are not completely compressing tube against wall, they will allow air in or out. who makes your dosing pump?
