Could i use the refugium section as an ATO reservoir with Kalkwasser?

I can’t tell from the website or pictures. Call BRS, or maybe someone else will know?

Doesn't look like it.

Looks like the water has to flow through all chambers to get to the return section.

I mean you could put the pump in chamber before normal, then use the return chamber as an ato, but you'll be severely limited in size of chamber. You'll get maybe get two gallons of ato water in there
