Just throwing this out there. My 180g is on the main floor (single story ranch) sump is a DIY 125g tank in the basement. A couple of months ago I started dosing kalk using a brs 50ml minute doser on a digital timer. Took a while to get the amount dialed in but now its rock solid at 8 dKH regardless of what time a day I test (no monitor) I think the key to this working tho is having enough evaporation rate to be able to supplement enough kalk. I'm dosing 7200 ml of fully saturated kalk a day. Kalk I just mix in a 30g brute at 8tsp kalk to 4g RODI.
But after typing and rereading some posts this it probably wouldn't work for you due to the low pH. I'm not much at checking pH but the few times I have it's been 8.4
