Mag Test Kits

[Tank2379]

Any good Mag test kit out there that are easy and easy to read?

I used to be a big fan of Salifert.
But I've been using the Red Sea Pro kit and really liking the distinct color change for Mg.

Either of those are fine. And some say Elos, but I haven't used them.

I was using that one but have a hard time reading the syringe...

Elos is good.

Elos is good.

Do you have to use a Syringe or are we counting drops? I think it's easy with counting drops those syringes are confusing if your don't know what to look for.

This is what I've found

1) Shake each bottle before use.

2) Fill testing vial to 3ml using syringe.

3) Add Reagent A drop by drop, counting each drop while swirling the vial until the color changes from orange-red to green. The color change should be stable for at least 30 seconds. Make note of the number of drops.

4) Rinse vial, refill to 3ml using syringe.

5) Add 5 drops of Reagent B. Close vial with stopper and shake for a few seconds.

6) Remove stopper, add 0.15m of powder Reagent C with provided spoon. Close vial with stopper and shake for a few seconds.

7) Add Reagent D drop by drop, counting each drop while swirling the vial until the color changes from pink-violet to light blue. The color change should be stable for at least 30 seconds. Make note of the number of drops.

8) Subtract the number of drops in step 3 by the number of drops in step 7. Multiply the difference by 50. The resulting number is the amount of magnesium expressed in mg/lt (ppm).

Example: 30 drops minus 8 drops multiplied by 50 equals 1,100 mg/lt Magnesium.

It would be better to learn to read a syringe. When you go to counting drops the accuracy and precision go in the toilet.

Nothing quite as helpful as second hand hearsay :uhoh3:
