Adding Mg and still tests LOW

Hey! OK I've been adding Mg from Bulkreefsupply.com(sulfate &chloride) following the directions they have and when I test its WAY low. I'm using the Salifert Mg test. I follow the directions and it doesn't change color until the 2nd little syringe full. I drop by drop on the first syringe (the smaller of the two that comes with it), then have to refill it with Mg-3 to get the test to change color. what's up with that?

 

Im thinking that your not following the tester kit correctly.

 

WOW,

2ml of water from the short syringe in the bottle
4 drops of #1
1 level scoop of #2
stir
put the long thin syringe in #3, place all the way in and pull until the bottom of the rubber is at 1.0
add drops from the thin syringe in the bottle, stop when the color changes and read the bottom of the rubber o-ring and match it to the chart
if the color didnt change on the first syringe then the Mg is over 1500, at this stage one syringe=1500Mg
if your using the second syringe to have the color change then read the chart from the bottom of the rubber o-ring and add it to 1500.

 

Also, what date does the sticker say on top of the box?

 

02/2011

I'm following the directions to the letter and it takes two of the small syringes to get the color change

so, RG you're saying my Mg is well over 1500?

water change time?

 

Wow, yes time for wc

 

Pull off bout 10/15 gallons till you find out what or if your doing somthing wrong, watch for alk/ph

 

what is the mg number you are coming up with seems like you have extreemly high mg if I read those directions posted corectly

I personaly use the tropic marin ca/mg test kit and think it is very accurate

 

filling up my buckets as we speak my pavona seems to like the high Mg it's little finger are justa wavin

 

if and only if your following the directions to the letter and doing the test properly and the test kit is good and upto date with two syringes the Mg is 3000. please make sure your correct on your assumption that your Mg is askew before you proceed.
