Do I have the Mg problem?

[lastduke]

Randy, that was what I did. Do you think using Hardness Plus to boost CA could couse this CA drop? I don't have this problem after I used hadness plus to make part 1

It is calcium chloride I expect, and while I do not know if it is adequately pure to guarantee no issues with it, there should be no problem maintaining calcium with it.

So lets just track things going forward.

What is the calcium level now?

I checked the CA tonight, it was 340ppm, I dosed 10ml Part 1. Let's see what the results, I will make a trend to give you guys more information to help me troubleshoot.
thanks you for help

That is my Recipe 1? In a 30?

Use this calculator to determine the dose. That will only boost calcium by about 3 ppm.

You might need to add more like 120 ppm in a corrective dose, followed by another large one the next day.
