Dosing Kalc

[soapy]

No, the outflow from the ATO pump dumps into the kalk reactor, so the water flows through that and on into the sump. So whenever the ATO kicks in water is running through the kalk reactor.

Which of course is not ideal in my case since the pump which stirs the kalk comes on according to a set timer. So occasionally the kalk will be stirring up and then the ATO kicks in and stirred up kalk water is pushed into the sump. In a perfect system the kalk would be stirred in between or after the ATO pumps. You dont really want raw kalk in your tank, but so far I have suffered no ill effects that I can see. Using less kalk and having a bigger reactor help somewhat.

Like you suggest a controller would be a great way to coordinate a work around to this problem.
