Elos Magnesium Kit
	Rating: 4.67 Quantity in Basket: none Code: EO4129 Price:$27.99
	Quantity:
Magnesium (Mg) is present in a high quantity (1.300/1.350 ppm) in natural seawater. Contrary to its (not only quantitative) significance, this element was ignored as an important parameter of the marine aquarium for a long time. In contrast to that we know today that Magnesium creates a remarkable improvement in the growth of calcareous algae and also has a positive influence on the growth of invertebrates and macro algae.  The ideal value of Magnesium in the aquarium is: - for the seawater aquarium 1100-1300 mg/Lt  Because of the importance of Magnesium, it is necessary to keep inside our marine aquariums, the proper Calcium Level, testing it with an accurate test kit. ELOS AquaTest Mg, as well as all the other titrimetric test kit of this line, grants an high precision thanks to several procedures like the use of calibrated dropper with constant and predefined drops of 0,05 ml each, the validation of its quality, through NIST (National Institute of Standard and Technology) certified samples, in order to grant accuracy and constant results, the careful stock management to supply to our customers ONLY the most actual and fresh production batch.  HIGHLIGHTS: High quality system: one powder reagent and two liquids! Standard sensibility: 100 ppm of Magnesium ions. NIST validation: each batch is validated using NIST (National Institute of Standard and Technology) samples "C" reagent available as separate sales unit High number of test per kit: up to 60 tests (with a standard Mg level of 1100 ppm) "Safe reagents": reagents and testing procedures are based on Low Risk Reagents. None of Elos test kit are based on Toxic Reagents.

5 Good, complicated instructions	09/19/2009 - by Vincent Edwards from Bloomington, IN US
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.
4 Good Kit, Instructions not clear	06/29/2009 - by Mark B from Dubai, UAE
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.
5 nice and easy	10/04/2008 - by chris stewart from houston, TX US
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!!
