PM Kalk RX setup : any recommendations? (1 Viewer)

[ReefNoob]

I've been *dosing* kalk using top-off water mixed with kalk in my RO/DI jug.

Now,getting all pro,I got a PM RX and setup the way shown in the pic.
Basically,aqualifter pump still hooked to my ATO will lift from the RO/DI,into the reactor,then outlet of reactor goes into a control valve,then into a sponge filter and into the sump.
The MJ mixing pump will pulse for 15 mins twice a day to keep it concentrated.

Anything else I should be thinking about ? Improvement ideas welcome!

Thanks

Wait,no one? I can't be the only one dosing Kalk

I dose kalk with the exact same reactor. I use an aquamedic pump that pulls from my ro di tank. I dose 4 times a day for about an hour and 15 minutes each time. Be sure to watch your pH.

Cool thanks.
Do you dose based on your Ca needs only and you top-off with another pump? Or is it all in one?
How much pH deviation do you typically observe,if any?
