What order to dose cal, alk and mag

[AriMiko43]

I am running a bubble magus 3 part doser on my 156 gallon mixed reef tank. I am dosing alk and cal at 150ml a day on a 24 hour cycle. My mag is dosed 20ml a day every 2 hours. The order I am dosing is alk first then cal and then mag. My alk and calcium are still dropping every day. I raised my daily dosing to 200 ml and still see no change in alk or cal. I am using brs recipe 1, how is this possible that no change is being made? Am I dosing in the correct order?

what do you mean no change ? in the amount dosing ? or how levels or needs havent changed ? and what are your levels specific not guestimate, how i figured out my dosage with my bm 3 channel was i did a wc, and later in day tested, then tested before next wc and seen what tank usage was. and dosed accordingly

What I mean is my alk is 8.9 dkh, cal is at 420ppm and mag at 1350 ppm. I want to bring my alk to 9.6, cal to 430 and keep mag the same. I found my sweet spot on mag at dosing 20 ml a day. My mag stays at 1350 and doesn't change. As for my alk and cal I was dosing 80 ml a day and it was still dropping by 0.3 dkh a day, cal dropping 10 ppm a day. I raised my dosing to 150 ml a day just to get my levels back up but still no change in alk or cal. They are both still dropping the same amounts. Now I'm up to 200 ml a day and still the same. It's like my alk and cal will not go up. Am I dosing in the correct order or are they buffering each other out? It is real puzzling to me. I know my tank couldn't be using that much. I have mostly Lps, softies, a few clams and maybe 10 Sps.

150ml a day is a huge amount of 2-part to be adding. if you have been doing that for a while i would guess that is it just precipitating out of the water.
