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.
