So my Mag has been on the decline for the past 3-4 weeks and is now just over 1200. Picked up some Seachem Mag to dose it and the directions tell you to dose the ATO. That's easy enough, but my ATO feeds through a kalk stirrer so I wanted to see if putting water saturated with Mag into the kalk stirrer would be ok or if I should mix it in another container and manually add a cup every so often to dose the Mag.
