Dosing container DIY

[Gorz100]

Hi guys

I am currently starting automated dosing with my P4 Pro doser and am currently just using the redsea tubing for both the inlet and outlet. I would like to get some sort of metal tubing to insert into my ALK/CAL/MAG bottles but I can’t find the mm size required anywhere.
I am using the redsea dosing tubes that are 3mm internal and 5mm external. My stupid self cannot work out the right size hollow metal tube that I need! Is it a 3mm or 5mm hollow tube that I need for the inlet? Sorry for the dumb question!

Why metal? If you want rigid, I'd go with plastic. Between the potential chemical interactions of the dosing solutions and the presence of saltwater, I wouldn't use metal. I use soft tubing, but if you want rigid plastic tubing, there are many choices.

I’m not sure why I put metal, i essentially just meant something more solid than the tubing, just confused on diameter of the tube for them to connect properly

No clue on the size question but I can say most of what I've seen and read people are using acrylic tubing in the dosing containers, not metal.

1/4" Clear Acrylic Tube -16" Long

Why does BRS recommend this? Acrylic tubes have many different purposes. Using these for DIY projects like kalkwasser drippers, feeding tubes and they even can be used to help add support small aquascapes, it is always a good idea to have extra acrylic tubing on hand. 16" of clear acrylic tube...

Thank you, I wrote metal but I essentially meant something more rigid but that’s perfect, thank you
