I have a Apex 2016 including a trident. I'm currently dosing all for reef using a Kamoer X1 Pro. I also have a DOS that was intended for water changes that I've never used. Question I'm contemplating is whether I should sell it. Or does it work together with a Trident and dose according to the readings? If so can it work with all for reef? Or would I need to switch to 2 part?
