Sorry for a noob question, but why Neptune DOS only comes with two heads (for Calcium and Alk) only? Don't people usually dose 3 parts (Alk, Calcium, and Mag)?

So you have to buy two of the units.....
I use the dos for alkalinity and calcium and manually dose magnesium. Based on my trident readings I only need to dose magnesium 2x a month in addition to 2 water exchanges a month.oh that’s the only reason? It will be expensive to own two units of DOS. What’s other option that works with apex and trident?
