Default Calcium Reactors

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

It depends on the atmospheric CO2 in my home. In the summer I have no problem keeping my pH in the 8.1-8.3 range with a window open. In the winter I go down to 7.8-8.1 and I use both a calcium reactor and a kalkwasser reactor. Start slow and measure your alkalinity weekly. Once you get the reactor dialed in you can be more lax.

My pH stays okay just with the reactor.

Hint for them though, reactors used to maintain Ca levels, so supplement first to get your level where you want. Found pushing easy to spike the alk.

Ifyou add a second chamber to your reactor it helps too. Just put the calcium reactor media in the second chamber and you're good to go. It helps a bit.

Thanks all, i've got a second chamber for my reactor, i'll just see how it goes.

Didn't think about the initial setup, thanks for the tip, makes sense that you want the reactor to maintain the Calcium, so using it to build up in the beggining will not help dialing it in.

And i've heard that fresh air in the house makes a differance, didn't think it would effect the tank that much, might explain some movements i have right now.

I punched a hole in the side of the house so i could bring air in for my skimmer. Great in the winter took it off in the summer as i was getting funny ph swings with storms and when people sprayed there weeds.
