Magnesium!!

[michaelabellz]

So I’ve done multiple tests on my saltwater tank for magnesium and every time my tank reached zero. I assumed it was a flaw in the test kit because I’ve been adding reef salt which should contain high amounts of magnesium. I purchased a new test and tested my water but it reached zero again, so I decided to take a cup of my saltwater from the tank and add the reef sand right to it. I let the salt dissolve and then tested again for magnesium AND IT TESTED ZERO AGAIN!! Does anyone have any information on any of this or should I take this problem to my LFS?
The salt I’m using is Coral Pro Salt by red sea

What do you mean it reach 0?

You must be doing something wrong with the test.

My mag test you ad one reagent than slowly add the second when ever it turns a certain color you see how much is left in your needle and read the chart to figure out your mag level

 

[Reefing_addiction]

So if you use all of the second reagent you mag is actually pretty high the less you use the lower your mag is

 

[AlexStinson]

So are you saying you use the entire syringe?

So are you saying you use the entire syringe?

That’s what I’m wondering

 

[michaelabellz]

Yes I’m using the entire syringe and there has been no change in colour.

 

[michaelabellz]

And I have been adding it very slowly and swirling it after every drop.

 

[Reefing_addiction]

Yes I’m using the entire syringe and there has been no change in colour.

Than you mag is high not low

 

[Reefing_addiction]

If you use all your reagent and nothing left mag is 1500+
the number in black is what you used the number in purple is what’s left in syringe

@michaelabellz i had an oh duh moment when I figured this out. The first time or two I tested I just scratched my head. Every time I went to the LFS my mag was high at home I thought it was 0. Than I watched them do the mag test and a light bulb went off in my head!

Thank you so much for helping, i did realize that my test is slightly different from yours in a way that you have to calculate how much of the reagent is left instead of how much was used. So now that I have that figured out I can start to fix the high magnesium in my tank and get back on track. Again, thank you for all your help it means a lot.

Please tell us the kit you're using, also watch some YouTube videos on that kit, see if that helps.
