Doser help

[weiwencheng]

Well, like everyone else I have come across, I am sick of my aqua medic doser pump crapping out on me. I don't have the time to fiddle with it everyday so it works properly. it is hooked up to a cal reactor. I am looking for just a basic doser to siphon the water out of my sump and into my reactor, nothing fancy. It is going to run all the time. I have looked at the Spectrapure, but that is a bit of an overkill. Any ideas?

What kinda head height are we looking at?

I used a Aqua Lifter pump for my calcium reactor. Worked pretty good.

It is about 2ft tall from base of sump to where current aqua medic doser is.
