Need recommendation for small pump

[Bilk]

I need a small pump that can overcome a head of 5'6" from a kalk reservoir to the overflow of my tank. I'm doing this to increase the PH of the flow over the ATS screen which is supplied from the overflow. Pump must be submersible.

One option I think, is a Tunze metering pump for the Osmolator. That is if I can get it to work off of the breakout box connected to the Apex controller. Is this possible? The metering pump is 12v DC. I'd need help with the hookup and programming for this. Right now the two float switches are connected to the BB. The Tunze pump is good for 141" head.

Otherwise I need a small AC pump to get power from the EB8. The tubing is 1/8". I have a small utility pump but it can't overcome the head pressure to that height.

Eheim pumps.

or marineland pumps, you can adjust the flow on it too.

or 2x TOM Aqualifter pumps.

or a dosing pump

Why not a peristaltic pump?

Are the aqualifter pumps submersible?

Checking the Eheim pumps. The Tunze pump would be perfect but would like it to run off the BB.
