Yeah, time to get on that Mg and see if that's part of the issue here I guess.

For using the reactor for Magnesium see Zeomag being used also, not sure if easier to source than dolomite.

Not sure if I can/could recommend the Magflake from littleilvermax as only been using a little over a month, but found after getting the Mg in system up, it's staying fairly constant (1200-1300ppm, ELOS so don't have the resolution) . I haven't had to add to the display since the start and just been making sure the water for changes is at 1300ppm and it's seems in-expensive.

Back to the alk and MG. Found before I was testing and supplementing for Mg (assume ~900 ppm based on IO salt) my alk was 10dKH, (Ca 350-380). Now since adding Ca/Mg (testing at Ca 400-425 and Mg 1200-1300) in addition to reactor, finding if anything alk now steadily up also to 11dKH.

reading all this makes me want to get Salifert all in one Calcium
I think its Ok for tanks up to 70 Gal to keep up with the Calcium demand...

I use Rowalith C+ for media which is the same as the LFS use's. I used Epnson salts to bring my Mg up to where it should be. I would like to get a kalkwasser mixer to run at night to bring my ph up to a nice stead level.

I thinking of usiing a ph controled to maintane my ph level, but not sure that with work as planned. Ca reactor runs to bring down the ph and Kalk reactor come on when the ph drops. Hopefully that with work. I would set the ph at 8.4 to 8.2 and hope to maintane the Ca and alk level at the same time. I think that would work better if it could moniter the Ca and ALk level to where they should be. Pipe dream or I haven't built the computer to do this.
