Mg & Ca supplements

[CloudReefer]

Hi all, Ca and Mg dropped a ton while fighting some dinos (I won! so far anyway...) and are at 390ppm Ca and 1140ppm Mg. I just need to get both of those up without affecting pH, alkalinity or adding too much chloride or something else. I use All for Reef and just need to get my levels up and make small adjustments from time to time.

There are a ton of products on Randy's calculator - which ones are best for my application? You'd think this would be easy to search for but I haven't gotten the answers I'm looking for. Maybe my google-fu is weak. lol

Thanks :)

I would start with what’s avail at your LFS.
Take the calculator there and pick out what you need .

My main LFS didn't have any Mg or Ca that I saw on the shelves and with traffic a LFS stop during the week adds 45-60 minutes minimum to my commute. Would rather order it at this point.

That is interesting question:

I just need to get both of those up without affecting pH, alkalinity or adding too much chloride or something else.

I suspect there is nothing available that meets all of that.
Ca additives containing something mainly chloride.
Mg is the same and for example TM Bio-Magnesium has sodium, potassium and 70 trace elements…

Extra chloride you can correct with water change over time, the other extras as well.

Regardless good question, I am following along. Maybe there are some alternative methods.

Would Reef Fusion 1 work? I have only used Reef Fusion 2 to bring up alkalinity and have not had to dose anything to bring up calcium and magnesium yet.

It will increase Ca, but it has other things as well:

Interesting they don’t mention chloride, I am sure it is there as well.

I understand there won't be no impact to alk, ph, chloride levels etc.
I am just trying to make sure I don't kill anything.

My first thought was to use calcium chloride and magnesium chloride hexahydrate to make these adjustments, but I don't know how much chloride (chlorine?, ammonia?) will be added to the tank.

Then I figured kalk, but I would prefer to leave my alk right where it is.

So then I figured I'd buy a manufactured product to get things in line while I did more research, so that's kinda where I'm at. :)

Brightwell aquatics magnesion and calcion should do what you need. Just adjust over the course of about a week and you should be fine. I stared out with reef code A&B before I started all for reef, these have no trace elements added so it’s safe to use with A4R.

You can add more chloride without any harm.

Any suitable brand or diy that is calcium chloride is suitable for the calcium increase.
