:: Mg Magnesium Test for Aquarium
Magnesium is a major salt in natural seawater. Contrary to its significance this element was ignored for a long time. We know today that Magnesium creates a remarkable improvement in the growth of calcareous algae and invertebrates. In Marine Aquarium it is good practice to keep its concentration around 1.300/1.350 mg/lt. otherwise aqueous calcium ions (Ca2+) could bond with carbonates and not be available for corals intake. ELOS AquaTest Mg permits the precise measurement of Mg values thus permitting to perfectly dose our Magnesium additives.
Grading: each drop equals 50 mg/Lt of magnesium

(09/19/2009) - Here are a few tips for the instructions:
This is a color change type test, meaning you add drops while swirling the test tube until you get a color change. Twice.
This test is completed in TWO parts:
meaning you add 3 ml tank water and complete test 1 (around 30 drops if levels are good)
...then EMPTY and clean the test tube...
before you add 3ml of fresh tank water and do the second test. (between 4-6 drops if levels are good)
Oh, and then you subtract the drops it took to produce a color change for test 2 from the drops it took to produce a color change in test 1...
and multiply by 50 to get your levels. Fun stuff for sure.
The color changes are very fast and dramatic... no guess work involved.
Once you have done the test a few times, it becomes very natural and the results appear to be accurate to about +/- 50 ppm which is quite good.
Just be sure to take your time read the detailed instructions a few times before you do your first test... they are easy to misunderstand.
I'm still giving this test a 5 because it is very accurate and really isn't that big of a pain in the butt once you have gotten the hang of it.
I've used the salifert test kit as well, and it is also good, but
between the two I prefer this test by a small margin.
(06/29/2009) - This kit is very good. Clear colour change. no going over a colour chart.
My gripe is the instructions...It doesnt tell you clearly that you need to do the test in two phases using "tank water"
So basically its two separate tests to get the values...Both tests need to be done with water straight out of your tank.
i ended up frustrated and had to call international to ELOS to have them tell me this.
(10/04/2008) - I threw away my salifert kit after messing around with those little insulin syringes. This test kit is easy. 3ml water, 9 drops of reagent A, one scoop of power, count drops and bam!!
Easy color change!!
