Stabilizing Alk, Cal, Mag

DanielCervantes · May 16, 2018

I’m having trouble stabilizing the 3 major elements. I was doing great and I kept adding more and more corals. I would test and adjust the doser accordingly. But this past week I’ve tested them and they read as followed. Alk 8.7, cal 480, Mag 1520

I like to keep Alk at 8.3, cal at 430 and mag at 1420
I dose ESV on a bubble magus doser currently dosing 55ml Alk, 45ml Cal, 25ml Mag

I wouldn't be overly concerned with the numbers that you currently have. 8.7 isn't far from 8.3 and the higher calcium isn't going to make or break anything. If you want it lower, I'd say just decrease the amount you are dosing slightly and let it level off to where you want it. Maybe start out with 10% less(just a random number not mathematical equations involved) and measure in a few days to see where you are.

I agree the current numbers are fine. If you want alk a bit lower, just dose a bit less of all of them.

Everything was stable to how I like it. Out of nowhere tank stopped consuming cal and mag.
I’m now dosing 25ml cal and 10ml of mag and it’s still hasn’t came down

I don’t think that is likely to be true ( that alk consumption remained unchanged and calcium and magnesium consumption dropped), but I don’t disagree that test results might seem that way. Don’t overly rely on short term trends in hobby kid test results, which are often noisy.

Especially magnesium, there’s no magnesium kit that can see day to day consumption of magnesium. Even week to week is marginal to detect.
