Anybody do this before?

Here is the question.

Until I get to Van and set up a proper RO resevoir for the tanks, what I want to do in the mean time is run my kalk stirrer in a loop within my tank. Having the minijet pump water from the sump into the stirrer and then have it dripped in a different part of the sump. Curious about it. Anyone ever done that? Any ideas about possible problems? Suggestions?

Once I can rig an effective dosing system using float switches within the system, this is how I want to add a bit o' kalk to make the mornin' great.. lol
