I see a lot of dosers to buy that have 4 doser pumps. I get alk, calc, mag, but what is the 4th for?

I have BRS doser for calcium, but I'm finding that I need at least 2 more for alk and magnesium. there are a lot of 1, 2 or 4 configurations. reefbreeder tech support said they use the 4th for trace elements. I there's probably a lot of other uses. I have 2 open drive port slots so I could use 2 hydros dosers there. My ph swings from 8.21 to 8.35 in a day. dose about 50ml/day for alk. At the moment, I'm just trying to decide what is right doser to acquire.

How accurate are these dosers for small tanks where only 5 ml per day is required?

red sea doser seems really nice. it has a .05ml accuracy. there is a new doser by Jabeo. it is really cheap. 4 doser pumps for like the cost of single doser pump of other vendors
