Hi Mitch,
Dosing pumps are not designed for moving this amount of water volume, it is also a rather expensive option.
We advise the use of a small "cheap" hobby pump for this purpose.
In smaller tanks you can use the doser for ATO but again even this is slight over kill.
Dosing pump applications are best kept for the use in trace element dosing, ballings salt dosing, and general additive dosing
Hope that helps
