Comments: Nice test kit, very easy to use. The only problem is if you are trying to raise your mag above normal levels to choke out an algae problem it can't read that high. I was attempting to raise the mag to 2000 ppm, but the kit only reads up to 1500 ppm.

Comments: The information in the pamphlet which comes with the test was very informative and the test itself was straight forward and easy to perform.

Comments: vI just received my new RS Mag test kit and would like to give you all a review. When I un-packed it the Packaging impressed me with its, "well beautie?" Also it is a very professsional "looking" test kit. This actually makes me leery I sometimes feel they are covering up something with the package, "Dave shrugs" but after using the test I do feel differently. I know pretty much where my Magnesium level is presently, "think stratosphere" I used Saliferts great kit to obtain the level and wanted to see how close they would be. The instructions I used are the little card that is in the box, you can find a video of how to use the kit at Red Sea's site which I watched and it is a very good video. The test is straight forward and easy, it took maybe 4-5 minutes? The end result where you have the final color change I feel is easier than the Salifert, very distinct when the change from a pink to a blue happened. When I use Saliferts test I sometimes miss the change by a drop or two, "I'm also a bit color blind so the distinct change is nice". The syringe you use to do the final is placed in a device to hold it steady and it for me made it quite easy. The final result was within prolly 50-100 of what I got from Salifert and that for me is fine. So I give this unit a solid thumbs up! If you are in the market maybe try one out you might like it.Now the disclaimer; I am just a hobbiest, not an expert by far, and these are just my honest observations.God Bless,Dave

Comments: When you first open up the box the kit may look little intimidating. But take a deep breath and read the instructions (you can also go to Red Sea's website and watch a video of the test being performed. Either way it is an easy kit to use.
