Elos Magnesium Aqua Test Kit

SKU: 205142


  • A must HAVE! By FishWhisperer on 12/11/2014

    this is the first Mg elos kit i have used and it works great. It involves a bit more work to set than the previous kits i have used in the past (Salifert). If you are looking for a way to stop guessing how much mg you need to dose, then this is the kit you want to get. Highly accurate and reliable. A must have for serious reefers! Will purchase again when salifert is unavaible.
  • Annoying By Jason on 11/30/2014

    The test kit does it's job however it has too many steps. Like others have mentioned it requires that you put 30+ drops of the first solution then wash out the container and do a second test. Although i do prefer some Elos test kits, this is one I won't buy again. The Salifert Mg kit is more accurate and easier to use. One positive of the Elos kit is the dramatic color change from orange to green on the first step of the kit and pink to blue on the second part.
  • DO NOT WASTE YOUR MONEY<---Pro Tip By Quinn on 4/11/2014

    I work in the water testing industry so I believe my advice should be taken seriously on this one. DO NOT buy this test kit.
    The actual number of steps required to get an "accurate" result are tedious as well as error inducing. I previously, and will stick with, used three other test kits for Magnesium: Red Sea= OK, Salifert= Excellent and LaMotte=Ok. Simply put YOU WILL NOT get accurate results with this ELOS test kit because you are forced to use 30-40 "drops" per test...never an accurate measurement to use. The more drops you are required to use, the less accurate the result. Then to top it all off the results are given with an accuracy of +- 50 ppm!!! Which means you can be off by upwards of over 100 ppm!! Useless to say the least.
    To add insult to injury, the test vial lasted exacted one test due to the over sized cap required to stir the results. Broke the vial while using extreme caution and over 2 decades of water analysis experience.
  • Requires a 6th grade reading level By Johnathon on 11/12/2013

    This test does require a higher level of attention when reading the instructions but they do make sense. If you take your time, read it carefully and do the test right you will get a much better reading with much easier to notice titrations than the competitors test kits.

    Basically if you can get past the somewhat complex instructions you will find your Mg readings to be more accurate!

  • hard By Adam on 6/22/2012

    I didn't think it is very user friendly but what do you expect for a test
  • Excellent By Jim on 6/24/2011

    Great test kit. Directions are very clear and easy to read. The color changes during testing are easy to see.
  • Excellent test kit By Michael on 5/25/2011

    The written instructions are a little confusing but some online searching gave me answers that cleared up questions.
    I gave it 4 out 5 on recommendation because of the way the instructions read and a new comer to the hobby who is already intimidated by the chemistry side is going to get frustrated if they try this kit as their first experience testing mg.
    But it's a great kit and very accurate.
  • good test By roger on 4/22/2011

    the mg test is a lil time consuming but thats what its going to be. i personaly liked the instruction. very simple no reading and getting confused or multiple testing opions like in my salifert kh and ca testers. hard to screw up with pics and a couple of numbers. I have used this tested quiet a few times now and can get my mg number in no time
