Neptune DOS

[canadianeh]

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.....

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?

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.

I'm sure that's not why I run Alk and Cal then Mag on different doser

Primarily because Alkalinity and Calcium are the two dosed the most. Magnesium doesnt need to be dosed nearly as much as it's not consumed as rapidly as the others. The DOS can also function as an auto water changer. One head to take out water and the other to put in water.

That’s the conspiracy theorist’s reason! lol

In my opinion, a three-head unit with their current design would be way too large. It’s already super chunky, like 11” across.
Adding another head, let’s say making it 16”, would be too big to fit in many cabinets.

The closest competition may be the upcoming Ecotech Versa. It is coming out soon, advertised as a high quality single head WIFI dosing pump for $150. But it won’t interface with the apex, so I am not interested.
