    I am looking online to purchase a new test kit for magnesium....i'm looking at either Elos or Seachem. Just curoius to see what others thought of the brands and comments on using them. The Elos is about $10 less than seachem, but i want a good accurate consistant reading.

    I've read enough threads like this that *I* would feel confident any one would be a good choice. ;)

    I hear that.

    I use the Seachem Reef Status Mag kit. I like it. Easy to read.

    I've got to second this. I've used Red Sea for other tests like alk, N03 etc and was not impressed But I got into a crunch a month ago and ordered a RedSea Mag test. IMO as long as you follow the instructions to the tee it's pretty accurate. The color change can be a little challenging but I've not had problems with mine so far. Salifert is my usual brand tho.

    For the Mag kit, Red Sea isn't all too bad with the color change; you just needa pay attention and take it slow. It's nothing like their Alk kit, where the color never turns to the "finish" color, just straight to "over".

    I have the Seachem kit also, Seachem is the only manufacturer that has a reference solution to see if you are performing the test properly. It is easy to use also.

    or stays yellow even after you add the full second syringe LOL

    Mag kit is great
    Calc Pro is great
    Phosphate is great
    Nitrate is great

    so I have 4 Red Sea kits I am very happy with and one that is dissapointing

    Salifert for me.
    The Elos is ok but not as easy to use. If your MG is above 1500 the Elos will read it. I think the Salifert doesn't go that high on the scale.... so as long as your Mg is normal salifert is fine.
    I haven't used the others.

    my salifert only measures to 1500. 1600 = 1500 in this kit.

    but... so what :) I only keep at 1450-1500 anyway

    You can use the Salifert to easily measure above 1500. You just fill the syringe up all the way again. When you start dropping it in, it will eventually change color. Add these results to 1500 from the first test.

    Here are easy to follow instructions for a Salifert kit to measure greater than 1500:

    1. Follow instructions for one test to 1500 (full syringe).

    2. Fill another Syringe and add drops until color changes.

    3. Use the chart and find the value. Add this value to 1500.

    For example, if you get to 150 on the second syringe, add 150 to 1500, and your Mag is 1650!

    You can put the leftover contents of the syringe back in the bottle from whence it came.

    That is how the Seachem test works as well for over 1250.

    Thanks! I did not realize that.

    Over 1250? Sheesh. Thanks for the 'don't use Seachem' tip ;):cheesy:

    Heh. Well if filling a syringe to 1ml again is tough, then you're welcome! :)
