hi all new members here. I’m recently starting to dose my 16 Gallon Nano tank with Seachem Reef Fusion1&2. I’ve been doing it by Hand and would like to get a dosing pump. My question is besides the pumps and tubing do I need anything else? Such as a dosing container or can I just put the tubing in into the bottle directly? Any help would be greatly appreciated as I’m trying to keep the cost down which is not always the easiest thing with this hobby.
