High quality test kit By Jsl on 7/15/2016

High quality and pretty easy to use. Gives an accurate reading once you know how to test properly. Red Sea should clarify in the directions that it's normal for there to be an air bubble in the syringe to account for the tip..and to level the plunger with the 1ml line still.

its a little cumbersome with too many pieces but they are well made. Takes time ti get it down but eventually gets easier
End colors wrong and will change By James on 7/6/2016

I loved this test when I first got it. But as I used it and as time went by I noticed things that weren't right. After wondering what the end color really should be, I asked Red Sea. Apparently the end color for the alkalinity test is pink, not red. And it's not even pink, it's clear. The end is as soon as you see any pink at all. Which mean my measurements have been off the whole time. Then there's the expectation. As it gets older the end color for the alkalinity test changes. It's been about a year and the end color is now yellow, it never even gets close to pink or red. The bottle says "Exp. 0517", it's 0716. They also said the Mg and Ca end colors are when you see the first sign of blue, not purple and dark blue. Now I have no idea what to expect from this test and will have to get a different kit to see what my levels are. I don't think I'll be buying anything else from Red Sea any time soon.
Awesome kit! By Erik on 3/29/2016

This is an awesome test kit, once you get the hang of how to perform the tests, seems complicated but it is not. Pretty accurate and keeps my reef happy! Only thing I don't like is, it's hard to get everything to fit back into the black box once you take it out!

Very easy to use test kit. Also the price is great compared to buying each test kitCRESTWOOD individually.
Magnesium test doesn't work By Brian on 3/25/2016
Brian wouldn't recommend this product to a friend
Been reefing for over 3 years now, and I got this product based on BRS recommendation. I like the titrator, but test results are very inaccurate. I do not dose magnesium at all, so there is zero reason as to why my magnesium levels should be any higher than my salt mix (I use reef crystals) but EVERY time I have tested with this kit my magnesium reads 1600 ppm. That is absolutely impossible, magnesium doesn't form out of nowhere in the home aquarium. I can see ALK and calcium levels differing due to many different factors, but not magnesium. Beyond frustrated. Wish I would have just spent the extra $70 and got Hanna checkers for all of these.
Bad kit By Todd C. on 3/10/2016

The alkalinity test color chart shows are dark red upon complete titration, but no matter how far you take the test, I've never seen anything but a light pink. So this test parameter (for alk) is worthless to me.
Easy & Accurate By Jeffrey on 2/18/2016

I've used API and Salifert before and this is my go-to for Mag, Cal, Alk. Very easy to do and accurate. Very well made too. I like that this is a kit, and a box that stores everything and you just buy re-fills when necessary.

when I first got it I was intimidated with everything included, but after reading and watching youtube videos it couldn't be easier
got a bad batch By Kevin on 2/16/2016

I like the quality of the test components but my Alk test is hard to read because it changes from blue to orange to yellow instead of blue to red. I contacted Red sea via email but got no response. CA and MG test work great. I wish red sea would replace my alk test but I can't get a hold of them. Will buy different test when I run out of CA and MG test solution. I have been using the Hanna Alk test and love it!
