Calcium Reactors

[Lampshade]

I'm setting up a new tank next week and have a calcium reactor all ready to go. My question to people with reactors: Do you suppliment to raise PH? Would it be worth running a kalkwasser reactor for auto top off to help balance my PH? My tank's going to start pretty lightly loaded, VERY light loaded for calcium since most coral is LPS right now. Should i just set a slow drip and see how it goes? I've got everything to set up a DIY kalk stirrer, would it be worth building into my ATO system? Any feedback would be great, thanks
