Using both Calcium & kalk reactors

[Hockeydad]

Curious if anyone is doing it and with what results?
Currently runing a knop but ph is 8.15 during day and 7.85 in evening. Have a refugium with 24/7 lighting.
Would like to consider kalk reactor to raise ph.
Thanks

I run a Geo 618 Ca reactor and drip kalk daily.

My pH ranges from 8.0-8.2 even with a pretty potent kalk slurry.

Before kalk, my pH would get as low as 7.8.

All paramteres are pretty consistent now and favorable for SPS.

I use both and let my system top off through the kalk reactor at night. Always keeps the pH at about 8.2.
