Neptune Dos

[flipb18b]

I’ve been thinking about picking up a third Neptune Dos to dos magnesium. I currently have one for alk and calcium and one setup for auto water changes. My question what else is everyone dosing in a setup like this? Or is everyone just using the one pump on the third unit

I have 6 units for 2 tanks. Two in each tank for Aquaforest 3 part dosing (Alk, Ca, Mg) and the 4th for NoPoX. Two in my RODI station for AWCs for each tank. Expensive but effective.
