I wouldnt dose your alk and calcium thru an ATO. It will damage the pump very quickly, and it's not really a good way to measure how much is really going in.
This is what I use:
BRS 2 Part Doser
I have the alk dose 2 times a day. 12 noon and 12 midnight
I have cal dose 2 times a day at 5am and 5pm
I manually add mag when necessary
They are spaced out so they dont interfere with each other chemically, and it slowly drips 1.1 ml per minute, so no spikes. You will have to figure out what your tank demand is, and then set up some timers, or add them to a controller if you have one. Right now my demand is around 70ml a day for each using BRS 2 part mixes. So the pumps runs in 2, 30 minutes intervals for each.
Once I added these to my system everything got really happy. Best $170 I spent on the tank. Stability is key, and this will make that happen.
