Thanks for your responses, guys. I guess I didn't make it totally clear: I dose Kalk in specific amounts (3 minutes of saturated solution every hour, i.e. 24 times a day). This keeps up with evaporation this time of year. I keep the kalk solution saturated via an Aquamedic kalk stirrer. Yesterday I dropped the kalk timing to 2min 40 sec avery hour. I have a separate topoff that adds straight RODI water to the sump if the kalk additions don't keep up with evaporation. I guess now that I dropped the kalk times, the ATO will add some water....

Yesterday I also unplugged the Alk doser from the Reefkeeper. I am still dosing the same amount of CaCl2 and the reduced amount of Kalk. I will test again tomorrow. If you have any thoughts, I'd love to hear them.

Thanks for that article DCW1SFU. I read it many times. What confuses me is the fact that the article says to always add the same amount of Ca and Alk. It specifically says to resist tinkering with the amounts. If I did that, my Alk would be through the roof!...
