Alternatives to Calcium Reactor?

[CCK_8814]

So I had a scare with my ATO today which I run kalk in and it just made me want to switch over to a Calcium reactor even more. Just to make it known this was not my ATO’s fault or a malfunction. I was working in the sump while some coral was floating in bags in my display that then ended up stuck to the teeth of my overflow not allowing the display to drain into the sump fast enough causing ATO to kick on. So it did exactly what it was supposed to do. However, my problem is that I do not have the room inside my cabinet stand or in the area outside of my tank to fit and store both the reactor and CO2 tank (tank sits in corner of living room between 2 couches so space is tight, pic attached). Before I just switch to Dosing I was hoping people with a little more knowledge could educate me on some other options. Maintaining Alkalinity is not an issue in my tank for some reason, however calcium and pH were always low until I started running kalk in my ATO water. Currently I am carbon Dosing manually every evening but that’s all I’m Dosing at the moment. Tank is mostly SPS dominated with good amount of LPS and some BTAs.

Any and all suggestions and feedback appreciated. Full tank specs are:

20x20x20 Cube
Custom 19x19x16 Aquatics America Sump
Kessil A360WE
2x ATI Blue+ T5’s
Jebao DC Return Pump
Bubble Magus Curve 5 Skimmer
Vortech MP10
Icecap Gyre 1K
Calcium 440-450
Alk 9.7-10.0
Mag 1380
Nitrate ~10
Phosphate 0.03-0.05

Your ATO will be needed regardless if you use kalkwasser or not. Not sure why you want to go calcium reactor unless your not able to keep up calcium and alkalinity.

Try 2 part dosing to maintain your levels.

2-part (which is really 3-part) with the use of a dosing pump.

The ATO is part of my setup, I don’t plan on removing it. I would only like to stop running kalk in my top of water and switch to another way of maintaining calcium & Alkalinity. Sorry if that wasn’t clear in my original post.

That’s what I’m thinking may be the best bet. Just figured I’d see if any other options were out there.

Ok thanks. My Alkalinity never really seemed to drop prior to running kalk in my ato so I guess once I stop using it I’ll need to monitor to see how much it drops so I can dose accordingly. I run RedSea blue bucket salt but no matter what I do my alk has never gone below 9 (even before kalk) and usually rises at least .2 between weekly water changes. If anyone else has other alternatives I’m still open to suggestion!
